Precoding for RIS-Assisted Multi-User MIMO-DQSM Transmission Systems

Precoding for RIS-Assisted Multi-User MIMO-DQSM Transmission Systems

This paper presents two precoding techniques for a reconfigurable intelligent surface (RIS)-assisted multi-user (MU) multiple-input multiple-output (MIMO) double quadrature spatial modulation (DQSM) downlink transmission system. Instead of being applied at the remote RIS, the phase shift vector is a...
