Abstract

Abstract

A squaring method to find the maximal-ratio receive combining scheme of the orthogonal space-time block codes is presented. Furthermore, it is proved that this method can be used as a general method for the orthogonal space-time block codes. Considering the orthogonality, the minimum distance decisions for each output branch can be made respectively. The performance using this method is the same as that using the maximum likelihood decoding criterion while the complexity of decoding is much lower.
