On precoder design under maximum-likelihood detection for quasi-stationary MIMO channels
We consider the problem of constructing linear precoders for quasi-stationary multiple-input multiple-output channels. We assume maximum-likelihood detection and the objective of the precoding is to maximize the minimum Euclidean distance of the signaling. Since the channel remains constant for some time, the precoding can be performed spatially as well as in time. As will be shown, the precoder d
