Description: This paper deals with optimizing a transceiver, which consists of a linear time invariant (LTI) matrix filter at the transmitter and a decision feedback (DF) receiver, for single-carrier data transmission over multi-input multi-output (MIMO) intersymbol interference (ISI) channels. Considering a spatial multiplexing approach for transmission of multiple scalar substreams, we adopt some cost function f0 {MSE i }) to measure the overall system performance, where MSE i 's are the mean-squared errors (MSE) of the substreams. It is proven that for any cost function f0 the optimum transmitter is of the same specific structure and the original complicated variational optimization problem can be drastically simplified to a problem with scalar variables. The solution can be further simplified if the cost function is specialized to the cases where the composite function f 0 o exp is either Schur-convex or Schur-concave.
