Diversity Analysis and Design of Space–Time Multiblock Codes for MIMO Systems Equipped with Linear MMSE Receivers

This paper addresses the problem of designing optimum full-symbol-rate linear space–time block codes (STBC) for a multi-input multi-output (MIMO) communication system with $M$ transmitter and $N \geq M$ receiver antennas and a linear minimum mean square error (MMSE) receiver. By analyzing the detection error probability expression for the optimized STBC, it is shown that for QAM signaling, the maximum diversity gain for such a system is …
