Spatial beamforming is an efficient way to realize dual-functional radar-communication (DFRC). In this paper, we study the DFRC design for a general scenario, where base station (BS) simultaneously detects target as multiple-input-multiple-output (MIMO) radar while communicating with multiple multi-antenna communication users (CUs). This necessitates joint transceiver both MIMO and multi-user (MU-MIMO) communication. order characterize performance tradeoff between MU-MIMO communication,...
TeraHertz (THz) communications can satisfy the high data rate demand with massive bandwidth. However, severe path attenuation and hardware imperfection greatly alleviate its performance. Therefore, we utilize reconfigurable intelligent surface (RIS) technology investigate RIS-aided THz communications.
