New project granted to the ELCA and MS3 groups

Wednesday, 23 March 2022

A new project sponsored by NXP and TKI entitled "Distributed High-Resolution Automotive Radar for Autonomous and Secure Mobility (DiRAc)" is granted to the ELCA and MS3 groups of our department.

Advanced driver assistance systems (ADAS) are transforming cars into securely-connected, highly-autonomous vehicles with the capability of sensing the environment, thinking, and taking adequate decisions in a huge number of traffic conditions. Enabling components of ADAS are radar transceivers permanently measuring the range, angle, and velocity of objects around the vehicle. The penetration of radars into urban scenarios requires extremely high angular resolution to separate pedestrians, bicycles, pets and even smaller targets.

Angular resolution is a challenge for single mmWave radars of limited aperture size. That is why in this new joint project with NXP Semiconductors we will therefore pursue a distributed, synchronized network of small aperture radar sensors in this research project. It deals with high-resolution imaging of the environment using a moving platform, wideband mmWave signals, and multiple distributed MIMO radars with a small number of antennas. Solutions for four critical radar architectural and signal processing challenges will be pursued: Imaging topology, waveform and radar synchronization, 360 degrees image focusing, and bistatic signaling. Two PhD students (one at ELCA, another one at MS3) will work for this project.

On Wednesday, August 26th, 2020 Yanki Aslan, the Ph.D. candidate in the MS3 group, successfully defended his Ph.D. work entitled “Antenna Array Synthesis and Beamforming for 5G Applications: An Interdisciplinary Approach” and graduated cum laude.

Congratulations to Yanki for this excellent result!

Now dr. Aslan will continue to work within the MS3 group as a postdoctoral researcher on a project in collaboration with the European Space Agency (ESA).

Abstract:

Realization of the future 5G systems requires the design of novel mm-wave base station antenna systems that are capable of generating multiple beams with low mutual interference while serving multiple users simultaneously using the same frequency band. Besides, small wavelengths and high packaging densities of front-ends lead to overheating of such systems, which prevents safe and reliable operation. Since the strict cost and energy requirements of the first phase 5G systems favor the use of low complexity beamforming architectures, computationally efficient signal processing techniques, and fully passive cooling strategies, it is a major challenge for the antenna community to design multibeam antenna topologies and front-ends with enhanced spatial multiplexing, limited inter-beam interference, acceptable implementation complexity, suitable processing burden, and natural-only/radiative cooling.Traditionally, array design has been performed based on satisfying the given criteria solely on the radiation patterns (gain, side lobe level (SLL), beamwidth etc.). However, in addition to the electromagnetic aspects, multi-beam antenna synthesis and performance evaluation in 5G systems at mm-waves must combine different disciplines, including but not limited to, signal processing, front-end circuitry design, thermal management, channel & propagation and medium access control aspects. Considering the interdisciplinary nature of the problem, the main objective of this research is to develop, evaluate and verify innovative multibeam array techniques and solutions for 5G base station antennas, not yet used nor proposed for mobile communications. The research topics include the investigation of (i) new array topologies, compatible with IC passive cooling, including sparse, space tapered arrays and optimized subarrays, meeting key requirements of 3-D multi-user coverage with frequency re-use and power-efficient side-lobe control, (ii) adaptive multiple beamforming strategies and digital signal processing algorithms, tailored to these new topologies, and (iii) lowcost/competitive and sufficiently generic implementation of the above array topologies and multi-beam generation concepts to serve multiple users with the same antenna(s) with the best spectrum and power efficiencies. This doctoral thesis consists of three parts. Part I focuses on the system-driven aspects which cover the system modeling (including the link budget and precoding), propagation in mm-wave channels, and statistical assessment of the Quality of Service (QoS). Although separate comprehensive studies exist both in the field of propagation/system modeling and antennas/beamforming, the link between the two disciplines is still weak. In this part, the aim of the study is to bridge the gap between the two domains and to identify the trade-offs between the complexity of beamforming, the QoS, and the computational cost of precoding in the 5G multi-beam base station arrays for various use cases. Based on the system model developed, a novel quantitative relation between the antenna SLLs/pattern nulls and the statistical QoS is established in a line-of-sight (LoS) dominated the mm-wave propagation scenario. Moreover, the potential of using smart (low in-sector side-lobe) array layouts (with simple beam steering) in obtaining sufficiently high and robust QoS, while achieving the optimally low processing costs is highlighted. For a possible pure non-line-of-sight (NLoS) scenario, the system advantages (in terms of the beamforming complexity and the interference level) of creating a single, directive beam towards the strongest multipath component of a user are explained via ray-tracing based propagation simulations. The insightful system observations from Part I lead to several fundamental research questions: Could we simplify the multiple beamforming architecture while keeping a satisfying QoS? Are there any efficient yet effective alternative interference suppression methods to further improve the QoS? How should we deal with the large heat generation at the base station? These questions, together with the research objectives, form the basis for the studies performed in the remaining parts. Part II of the thesis focuses on the electromagnetism-driven aspects which include innovative, low-complexity subarray based multibeam architectures and new array optimization strategies for effective SLL suppression. The currently proposed multi-beam 5G base stations in the literature for beamforming complexity reduction use either a hybrid array of phased subarrays, which limits the field-of-view significantly or employ a fully-connected analog structure, which increases the hardware requirements remarkably. Therefore, in the first half of this part, the aim is to design low-complexity hybrid (or hybrid-like) multiple beamforming topologies with a wide angular coverage. For this purpose, two new subarray based multiple beamforming concepts are proposed: (i) a hybrid array of active multiport subarrays with several digitally controlled Butler Matrix beams and (ii) an array of cosecant subarrays with a fixed cosecant shaped beam in elevation and digital beamforming in azimuth. Using the active (but not phased) multiport subarrays, the angular sector coverage is widened as compared to that of a hybrid array of phased subarrays, the system complexity is decreased as compared to that of a hybrid structure with a fully-connected analog network, and the effort in digital signal processing is reduced greatly. The cosecant subarray beamforming, on the other hand, is shown to be extremely efficient in serving multiple simultaneous co-frequency users in the case of a fairness-motivated LoS communication thanks to its low complexity and power equalization capability. Another critical issue with the currently proposed 5G antennas is the large inter-user interference caused by the high average SLL of the regular, periodic arrays. Therefore, in the second half of Part II, the aim is to develop computationally and power-efficient SLL suppression techniques that are compatible with the 5G’s multibeam nature in a wide angular sector. To achieve this, two novel techniques (based on iterative parameter perturbations) are proposed: (i) a phase-only control technique and (ii) a position-only control technique. The phase-only technique provides peak SLL minimization and simultaneous pattern nulling, which is more effective than the available phase tapering methods in the literature. The position-only technique, on the other hand, yields uniform-amplitude, (fully-aperiodic and quasi-modular) irregular planar phased arrays with simultaneous multibeam optimization. The latter technique combines interference-awareness (via multibeam SLL minimization in a predefined cell sector) and thermal-awareness (via uniform amplitudes and minimum element spacing constraint) for the first time in an efficient and easy-to-solve optimization algorithm. Part III of the thesis concentrates on the thermal-driven aspects which cover the thermal system modeling of electronics, passive cooling at the base stations, and the role of antenna researchers in array cooling. The major aim here is to form a novel connection between the antenna system design and thermal management, which is not yet widely discussed in the literature. In this part, an efficient thermal system model is developed to perform the thermal simulations. To effectively address the challenge of thermal management at the base stations, fanless CPU heatsinks are exploited for the first time for fully-passive and low-cost cooling of the active integrated antennas. To reduce the size of the heatsinks and ease the thermal problem, novel planar antenna design methodologies are also proposed. In the case of having a low thermal conductivity board, using a sparse irregular antenna array with a large inter-element spacing (such as a sunflower array) is suggested. Alternatively, for the densely packed arrays, increasing the equivalent substrate conductivity by using thick ground planes and simultaneously enlarging the substrate dimensions is proven to be useful. The performed research presents the first-ever irregular/sparse and subarray based antennas with wide scan multi-beam capability, low temperature, high-efficiency power amplifiers, and low level of side lobes. The developed antenna arrays and beam generation concepts could have also an impact over a broad range of applications where they should help overcome the capacity problem by use of multiple adaptive antennas, improve reliability and reduce interference.

In Memoriam – Earl McCune (1956 – 2020)

Tuesday, 2 June 2020

In one of his last interviews, Earl told us that he was willing to fight a few persistent beliefs in the field of wireless communication. For instance, he was busy making 5G more energy efficient. A challenge in which, according to Earl, all links in the communication chain need to be overhauled. Being both a professor at TU Delft and entrepreneur in California, Earl was involved in several major projects in this field. In Silicon Valley, he followed the idea of building a single large switch in which the available power varies each time. At TU Delft he worked with various groups on a solution consisting of hundreds of smaller transistors of variable size.

The love for building things

One evening, when Earl was twelve, his father explained a few months’ worth of network theory of electrical circuits to him. From that moment on, Earl became enchanted by the subject. As a result, he worked on technology development in the field of radiofrequency and wireless design for more than 45 years, most of which he spent in industry. ‘I just love to build things,’ Earl told about that, ‘and I have seen a lot of what works, and what doesn’t work.’ Although he actually enjoyed his early retirement in California, he couldn’t do nothing. Because he still wanted to help solve society’s problems, he accepted a position as professor at TU Delft.

Warm personality

Earl will not only be remembered for his boundless enthusiasm for the improvement of systems, and the inexhaustible amount of knowledge he brought with him; more than that, Earl was a mentor, an inspirer, an adventurer and a warm personality who put a smile on many people's faces with his dry sense of Californian humour.

Else Kooi Award Ceremony for Masoud Tohidian (Electronic Research Laboratory)

Thursday, 23 March 2017

The 2017 Else Kooi Award has been given to Dr Massoud Tohidian during the Award Ceremony at ICT open in Amersfoort on March 22, 2017. The Award was given by professor Bram Nauta (University of Twente), chair of the Else Kooi Award Foundation. Dr Tohidian was granted with the award for his scientific research on high-performance super-heterodyne receivers that are implemented using a minimum of analog circuits.

Masoud Tohidian obtained his PhD in September 2015 at the Electronics Research Laboratory group of the EEMCS Faculty, Delft University of Technology.

The Else Kooi Award is an annual award for young researchers in the field of applied semiconductor research conducted in the Netherlands. The award comes with a prize of 5,000 euros.

Massoud studied high-performance super-heterodyne receivers at the system and architectural level as well as the most critical building blocks at the circuit level. As part of his project, he designed new approaches to especially the bandpass filter, realizing a performance that exceeded the state of the art by a significant margin on several key parameters. Furthermore, he integrated these filters in a flexible super-heterodyne receiver, verifying and demonstrating the performance that can be achieved through this approach.

The jury of the Else Kooi Award concludes that this work is a combination of high quality theoretical analysis, modelling, design and experimental verification at the system, architectural and circuit level, resulting in high performance filters and receivers with a high scientific impact as well as high industrial relevance.

A need to amplify and combine to enable 5G in higher frequencies

Thursday, 19 January 2017

Our society's social and streaming behaviour speeds up the need for 5G. Marco Spirito, Daniele Cavallo, Masoud Babaie and Andrea Neto (Microelectronics) are all working on the 'key building' blocks that will enable 5G systems in the near future. Advanced 5G solutions are targeted in the WhALE project (WAtt LEvel transmitters at mm-waves), which is backed by STW. Marco: "And of course, as scientists, we are working on the more challenging building blocks. We are looking for alternative solutions, something that the industry would find extraordinary. The goal is to move to higher frequencies and to transmit, instantaneously large volumes of data. The frequency shift will result in lower available power, which we need to fix with new amplifier concepts. To achieve this there is a need to amplify and combine in this project : smart combining technologies. We are also resourceful in using new 'stuff' like 3D printing in our solutions".

7 July 2016: Opening of CryoLab for Extremely Sensitive Electronic Measurements

Friday, 8 July 2016

The CryoLab of TU Delft's Faculty of EEMCS has been opened on Thursday 7 July by the dean Rob Fastenau. TU Delft scientists from the Tera-Hertz Sensing Group, Jochem Baselmans and Akira Endo, will be leading a team of young scientists and engineers working in the lab on astronomical instrumentation. The first instrument, DESHIMA (Delft SRON High-redshift Mapper), is being developed to be operated on the ASTE telescope in the Atacama Desert in Chile. The goal of the research is to create 3D charts of so-called submillimetre galaxies that, in contrast to 2D charts, also show distance and time.

The large number of superconducting detectors, and the advanced electronics developed at SRON, allows DESHIMA to map a very large volume of space at once. While Endo leads the development of DESHIMA, Baselmans will soon install the next cryostat for testing novel THz array antennas, that will enable his upcoming instrument MOSAIC to target multiple galaxies at once. In the future, the CryoLab is envisioned to also host new coolers from QuTech. Superconducting electronics used for astronomical instrumentation and quantum electronics have much in common, because they both push the limits of what can be observed.

Happy 2016!

As a result, data transfer is improved and energy consumption reduced. The TU Delft spin-off was taken over earlier this year by the American company Maury Microwave Corporation.

Jury chairman and President of the Executive Board Dirk Jan van den Berg praised De Vreede for his involvement with many spin-off companies and patent requests. The scientists received �valorisation bonuses� of �15,000 and �5,000 respectively.

Congratulations to Prof. dr. Sarro with her royal honour

Friday, 24 April 2015

Professor Lina Sarro, professor of micro-electronics at the Faculty of Electrical Engineering, Mathematics and Computer Science, has been made a Knight in the Order of the Netherlands Lion, in The Hague.

She received the award because of her original research that resulted in a large scientific body of work and because of her in-depth involvement with her many students. Her pioneering work in the 1980s in the field of infrared sensors led to international acclaim. Since 1987, she has been in charge of research into micro and nanosystems (MEMS and NEMS) at the Else Kooi Lab, which was known previously as the Dimes Institute for Microsystems and Nanoelectronics.

Professor Sarro has published more than 200 articles in scientific journals and has received awards for her work on several occasions. In 2004, she received the Eurosensors Fellow Award, in 2007 the AISEM Career Award, and in 2012 the IEEE Sensors Council Meritorious Award. She is also a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and a fellow of the Institute of Electrical and Electronics Engineers. She has been praised on account of both her scientific work and her unfailing commitment to providing teaching of a high standard.

To her students, from both inside and outside the Netherlands, she is a figurehead. This applies perhaps in particular to female students and academics. In 2005, Professor Sarro became the first female to join the TU Delft Council of Professors. She is dedicated to emphasising the role of female scientists, in the conviction that it is a waste to use only half of our scientific assets. Her outstanding scientific reputation ensures that her voice is heard in this, and in other issues.

Millimeter-Wave Transceiver Frontends for Broadband, Energy-Efficient, and Linear Phased-Array Systems

Masoud Pashaeifar

Millimeter-wave (mm-wave) communication systems have been considered as key enablers for developing the fifth-generation (5G) of a mobile network, offering high data throughput, low network latency, and improved link robustness. Taking advantage of mm-wave phased arrays empowers 5G communication systems to establish directional links with large bandwidths between the base station and user equipment. Despite its huge potential, mm-wave 5G has several natural disadvantages. The shorter wavelength of mm-wave signals results in lower penetrability, higher free-space path loss, and susceptibility to atmospheric attenuation, limiting coverage. Additionally, 5G systems, requiring high data throughput and complex modulation, face challenges such as increased receiver noise and sensitivity, reduced link budgets, and limitations in transmitter power and efficiency due to nanoscale CMOS constraints and high PAPR, which also impacts system reliability and thermal management.

Unlike the digital front-end and computing processors, whose performance and power efficiency are significantly improved by technology scaling, the performance improvement of the analog front-end (RF/mm-wave and baseband circuitry) mainly relies on circuits and architectural innovations. Luckily, operating at mm-wave frequencies unlocks new op-portunities to address its natural challenges and innovate beyond initial expectations. This dissertation introduces a series of innovative designs and techniques to enhance the performance and efficiency of power amplifiers (PAs) and transceivers for 5G mm-wave systems.
