Multiplexing More Data Streams in the MU-MISO Downlink by Interference Exploitation Precoding
WCNC, pp. 1-6, 2020.
In this paper, we focus on the constructive interference (CI) precoding for the scenario when the number of streams simultaneously transmitted by the base station (BS) is larger than that of transmit antennas at the BS, and derive the optimal precoding structure by employing the pseudo inverse. We show that the optimal pre-scaling vector ...More
