GRCon21 - RF Convergence with GNURadio

Presented by Yukang Fu, Jacob Holtom, Alex R. Chiriyath, and Dan W. Bliss at GNU Radio Conference 2021 RF Spectral Convergence, or joint radar-communications, has recently emerged as an important area of research, especially for the telecommunications sector. However, there is a significant amount of difficulty in implementing this class of systems in actual hardware due to the computational complexity and nuances of the algorithm. In this talk/poster, we successfully implement a previously developed RF convergence system using GNURadio and Ettus USRPs and perform over-the-air experiments that validate the functionality of the system. We present the GNURadio design and blocks, as well as our results and analysis of the experiment. By developing a GNURadio implementation, we validate the over-the-air functionality of the algorithm, as well as provide a powerful research tool facilitating over-the-air RF convergence experiments. https://events.gnuradio.org/event/8/
