Current research in wireless communication is beginning to focus on moving to THz frequency ranges as a solution to find the required bandwidth to cope up with the ever-increasing data rates. Significant advancement has happened at the device level and also in the communication theory aspects to close the THz gap. However, sophisticated real-time wireless test-beds are essential in moving the research in communication at THz frequencies forward. Xilinx radio frequency system-on-chip (RFSoC) devices that were recently developed, integrate multiple high-bandwidth data converters into an SoC. These RFSoCs have drawn much attention in fifth-generation (5G) wireless systems and radar systems as potential enablers of digital beamforming solutions that can support up to a few GHz of bandwidth. In this webinar, how these devices can be leveraged to build real-time platforms for THz wireless experimentation was discussed.

The online webinar commenced with a welcome and introduction about the speaker, Dr. Viduneth Ariyarathna given by the Staff Advisor of the IEEE SPS Student Branch Chapter of University of Moratuwa. The speaker started off the discussion by giving a brief explanation of the state-of-the-art in above 100 GHz wireless systems experimentation platforms. Next, he proceeded by giving an overview on the Xilinx RFSoC-based multi-channel, multi-GHz back-end which is currently being developed at the Northeastern University for enabling real-time ultra-broadband communication at above 100 GHz frequencies. Finally, the audience was given the opportunity to clarify discussed subject matter, during the 30 minute Q&A session. This interactive and interesting session concluded with the Vote of Thanks by the Secretary of the society.
