Multibit Quantized Precoding for MU-mMIMO
Getuar Rexhepi, Shreesal Shrestha, Christoph Studer, Giuseppe Thadeu Freitas de Abreu
We propose a novel multibit quantized precoding method for the downlink of multi-user massive MIMO systems with low-resolution digital-to-analog converters. The new method, termed multibit quantized precoding (MQP), enforces the finite-alphabet constraint through an l0-norm penal…
