Minimum Symbol Error Probability Low-Resolution Precoding for MU-MIMO Systems With PSK Modulation
Erico S. P. Lopes, Lukas T. N. Landau, Amine Mezghani
We propose an optimal low-resolution precoding technique that minimizes the symbol error probability of the users. Unlike existing approaches that rely on QPSK modulation, for the…

Discrete MMSE Precoding for Multiuser MIMO Systems with PSK Modulation
Erico S. P. Lopes, Lukas T. N. Landau
We propose an optimal MMSE precoding technique using quantized signals with constant envelope. Unlike the existing MMSE design that relies on 1-bit resolution, the proposed approac…
