Abstract: This seminar presents advances in adaptive, highfidelity RF architectures for communication and sensing systems operating under stringent hardware and power constraints. The first part focuses on lowlatency optimization algorithms for in-band fullduplex and distributed coherent communication frameworks, designed to improve spectral efficiency, synchronization, and power management in emerging wireless standards such as 5G/6G. These techniques integrate software-defined radio digital twining, amplifier linearization, and self-interference cancellation to achieve real-time, resource-efficient RF operation across low-C-SWaP platforms.

The second part explores advances in millimeterwave radar-based biomedical sensing, highlighting 3- D MIMO imaging and frequency-modulated continuous-wave radar for contactless vital-sign and heart-sound monitoring. Leveraging motionenhanced beamforming and spatially resolved vitalsign intensity mapping, these systems enable precise localization and multiperson tracking. Implemented using commercial off-the-shelf components, they emphasize efficient signal processing, error tolerance, and real-time adaptability to overcome hardware limitations.

Bio: Dr. Adarsh A. Venkataramani is a Postdoctoral Research Fellow in the Antennas & RF Laboratory at the University of New Mexico, in collaboration with COSMIAC. He received his M.S, and Ph.D. in Electrical Engineering from Arizona State University in 2018 and 2024. His research spans software-defined radios, beamforming, inband full-duplex communications, and mmWave/MIMO radar systems. He has contributed to the development of low-cost SDR testbeds for accurate device characterization, cooperative beamforming algorithms, radarbased biomedical monitoring, and multi-function RF architectures. His recent work focuses on RF sensing and communications through plasma channels to enable resilient interplanetary wireless links.
