New Sub Terahertz R&D Testbed for 6G Research
September 22 @ 1:00 pm - 2:00 pmFREE
Sub-Terahertz (sub-THz) frequencies (100-300 GHz) with extreme modulation bandwidths are part of early 6G research. This presents many unknowns. One of those unknowns is exploring the level of system performance that is achievable and reasonable given new frequency bands, extreme modulation bandwidths, and new waveforms. This webinar will provide insight into this by discussing new sub- terahertz system-level design and test challenges presented by 6G. EVM measurement results at 140 GHz will be shown with varying waveforms and bandwidths up to an occupied bandwidth of 10 GHz. Low Signal-to-Noise (SNR) ratios are a challenge for wide bandwidth waveforms at sub-THz frequencies. Preamble and pilot-aided synchronization and channel estimation will be discussed to achieve more robust demodulation in low SNR environments. Understanding and addressing channel impairments at sub-THz frequencies will be another challenge. Sub-THz channel sounding will be discussed and the testbed receiver will be customized with a real-time adaptive equalizer FPGA implementation to address channel impairments.
