MSE-Based Precoder Designs for Transmitter-Preprocessing-Aided Spatial Modulation Under Per-Antenna Power Constraints.

In this correspondence, we investigate mean-square-error-based precoder designs for transmitter-preprocessing-aided spatial modulation (PSM) multiple-input multiple-output (MIMO) systems. In contrast to the existing precoders that are designed almost exclusively under the average total power constraint (ATPC), we focus on design problems under more realistic per-antenna power constraints (PAPCs). ...
