Interference Exploitation Precoding for Reconfigurable Intelligent Surface Aided Multi-User Communications With Direct Links
IEEE Wirel. Commun. Lett., pp. 1937-1941, 2020.
In this letter, we study the multi-user multiple-input single-output (MU-MISO) transmission assisted by a reconfigurable intelligent surface (RIS). Specifically, for an arbitrary precoder employed at the base station (BS), by exploiting the concept of constructive interference (CI), we aim to design the phase shifts at the RIS such that t...More
