NSF SpectrumX invites you to attend Andreas F. Molisch’s second Radio Shop Chat, “Sub-THz Propagation Channels: Measurement, Modeling, and Impact on System Design,” on Wednesday, September 2 at 3 p.m. ET.

Registration is required and free.

Abstract

While it had long been assumed that (sub-)THz channels show little multi-path propagation, recent measurements have demonstrated the potential for rich multipath and thus significant dispersion in both delay and angle. This talk will briefly review several extensive measurement campaigns, particularly in outdoor environments. It then discusses signal processing methods for their evaluations, both Fourier-based and maximum-likelihood estimators, as well as cluster-based models to compactly describe the extracted multipath. Finally, the impact of the extracted results on required equalizer complexity in the receivers will be analyzed. The results demonstrate the possibility and necessity for tradeoffs in THz system design in a variety of situations, such as limitations on the available modulation formats even in high-SNR situations, and the need for per-subcarrier interference suppression.

This event is a follow-up to Molisch’s April Radio Shop Chat titled “Propagation Channel Measurements and Models for 6G in Urban Environments.”
