Abstract

We consider arbitrary rectangular QAM signaling in orthogonal space-time block code (OSTBC) diversity systems over correlated fading channels with Gaussian channel gains. We first decorrelate the physical branches into uncorrelated virtual branches to obtain a general moment generating function (MGF), from which closed-form symbol error probability (SEP) is then obtained for OSTBC with generalized complex orthogonal design (GCOD) and it is discovered that different information symbols may yield different SEP´s.
