Hello, I'm Ian Roberts.
I am a fifth-year Ph.D. candidate at the University of Texas at Austin. My research is in wireless communication.
I am a
first second third fourth fifth-year Ph.D. student candidate in the electrical and computer engineering program at the University of Texas at Austin.
I am fortunate to be supervised by Prof. Jeff Andrews and to be part of his research group.
I am also advised by Prof. Sriram Vishwanath and part of his Laboratory of Informatics, Networks, and Communications (LINC).
Along with many others, we are members of the Wireless Networking and Communications Group (WNCG) and the 6G@UT Research Center.
I am honored to have recently been awarded the 2023 Andrea Goldsmith Young Scholars Award by the Communication Theory Technical Committee (CTTC) of the IEEE Communication Society.
I am fortunate to have been selected as a National Science Foundation Graduate Research Fellow. I appreciate their support of my research and studies.
The GitHub repositories associated with several of my papers are listed below:
- Beamformed self-interference measurements at 28 GHz
- Spatial and statistical modeling of mmWave self-interference
- STEER: beam selection for full-duplex mmWave communication systems
- LoneSTAR: beam codebooks for full-duplex mmWave communication systems
I have created and released MIMO for MATLAB (https://mimoformatlab.com), a publicly available package for simulating multiple-input multiple-output (MIMO) communication. It is completely documented, and video tutorials are in progress.
I was recently affiliated with GenXComm (GXC), a startup that develops a suite of full-duplex solutions that enable simultaneous transmission and reception in-band for various applications. GenXComm was founded in 2016 by Prof. Sriram Vishwanath and Hardik B. Jain.
I received my undergraduate electrical engineering degree from Missouri University of Science and Technology in May 2018. I was involved in undergraduate research supervised by Prof. Y. Rosa Zheng on the topic of underwater acoustic communication.
I am a licensed amateur radio operator. My callsign is KE0QVW.
Ian P. Roberts received the B.S. degree in electrical engineering from the Missouri University of Science and Technology and the M.S. degree in electrical and computer engineering from the University of Texas at Austin, where he is currently a Ph.D. candidate and part of the 6G@UT Research Center and the Wireless Networking and Communications Group. He has industry experience developing and prototyping wireless technologies at AT&T Labs, Amazon, GenXComm (startup), Sandia National Laboratories, and Dynetics, Inc. His research interests are in the theory and implementation of millimeter wave systems, in-band full-duplex, and other next-generation technologies for wireless communication and sensing. He is a National Science Foundation Graduate Research Fellow.
My Ph.D. research aims to bring in-band full-duplex capability to millimeter wave communication systems by leveraging dense antenna arrays to mitigate self-interference in the spatial domain. I combine theory, practical knowledge, and measurements to motivate, develop, and validate my research in an effort to create full-duplex solutions that integrate into real millimeter wave communication systems.
My broad research interestes are in wireless communication and sensing; communication system design, optimization, and simulation; millimeter wave; full-duplex; satellite communication systems; array signal processing; radar; measurements and prototyping. I aim to develop technologies that advance next-generation wireless communication systems by combining theory, practical knowledge, measurements, and experimental proofs-of-concept. Once I am finished with school, I look forward to a career where I can continue to research, develop, and prototype wireless technologies.

- December 2022: Manan defended!
- November 2022: Ethan defended!
- October 2022: We submitted a paper that proposes a statistical and spatial model of mmWave self-interference based on nearly 20 million measurements collected with 28 GHz phased arrays.
- October 2022: I co-authored a 35-page book chapter on full-duplex that overviews fundamentals and highlights recent progress in the context of next-generation radios.
- August 2022: I was a visiting student with Prof. Chan-Byoung Chae’s Intelligence Networking Lab at Yonsei University.
- August 2022: Rajesh defended!
- July 2022: We present STEER, which tackles a similar problem as our work LoneSTAR. STEER can enable a mmWave communication system to operate in a full-duplex fashion by strategically selecting transmit and receive beams that deliver high beamforming gain in desired directions while coupling low self-interference. This is achieved by leveraging small-scale phenomena observed in our recent measurement campaign of self-interference. STEER provides a means to use beamforming to mitigate self-interference while also allowing the mmWave system to conduct beam alignment.
- July 2022: Akash defended!
- June 2022: We introduce LoneSTAR, an enabler of full-duplex mmWave communication systems through the design of analog beamforming codebooks that can deliver high gain and reduce self-interference. This allows a system to conduct beam alignment and use a single solution to serve any downlink-uplink user pair in a full-duplex fashion.
