On precoder design under maximum-likelihood detection for quasi-stationary MIMO channels

In English 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 design is
tightly connected to the theory of partial response signaling and
efficient precoders can be designed by usage of existing methods. The
decoding complexity will be controlled and can be maintained small.
