A New Paradigm of Precoder Design for Finite-Alphabet Inputs Based Communications

This paper proposes a pair of new linear precoder designs to reduce the high computation complexity in the context of multi-input multi-output communications with finite-alphabet inputs. We initially develop a high-performance mutual information maximization scheme using closed cut-off rate expressi...
