Abstract

A method is proposed to reduce the complexity of ML decoding for MIMO systems based on PSK constellation with two transmit antennas. We use the feature that the points of a PSK constellation form a finite group under complex multiplication to substantially reduce the decoding complexity. The proposed method of decoding is used for both BLAST systems and a new full-rate full-diversity space-time code. The proposed space-time code offers a high coding advantage and at the same time allows for a simple decoding algorithm.
