Yet another entropy power inequality with an application

In this paper we derive a generalization of the vector entropy power inequality (EPI) recently put forth in [1], which was valid only for diagonal matrices, to the full matrix case. Next, we study the problem of computing the linear precoder that maximizes the mutual information in linear vector Gau...
