A Low-Complexity Design of Linear Precoding for MIMO Channels with Finite-Alphabet Inputs

This paper investigates linear precoding scheme that maximizes mutual information for multiple-input multiple-output (MIMO) channels with finite-alphabet inputs. In contrast with recent studies, optimizing mutual information directly with extensive computational burden, this work proposes a low-comp...
