Vector Precoding for Gaussian MIMO Broadcast Channels: Impact of Replica Symmetry Breaking
The so-called "replica method" of statistical physics is employed for the large system analysis of vector precoding for the Gaussian multiple-input multiple-output (MIMO) broadcast channel.The transmitter is assumed to comprise a linear front-end combined with nonlinear precoding, that minimizes the front-end imposed transmit energy penalty.Focusing on discrete complex input alphabets, …
