Study of Linear Precoding and Power Allocation for Large Multiple-Antenna Systems with Coarsely Quantized Signals

Abstract

This work studies coarse quantization-aware BD ($\mathrm{CQA}-\mathrm{BD}$) and coarse quantization-aware RBD ($\mathrm{CQA}-\mathrm{RBD}$) precoding algorithms for large-scale MU-MIMO systems with coarsely quantized signals and proposes the coarse-quantization most advantageous allocation strategy ($\mathrm{CQA}-\mathrm{MAAS}$) power allocation algorithm for linearly-precoded MU-MIMO systems. An analysis of the sum-rate along with studies of computational complexity is also carried out. Finally, comparisons between existing precoding and its power allocated version are followed by conclusions.
