Abstract

The performance of space-time codes under channel correlation has been studied in detail recently, and a variety of results have been produced. In this work, we simplify some of the existing derivations as well as present some new results. One of the novel issues raised in this investigation is the loss of the uniform error probability (UEP) property of many codes in the presence of transmit side correlation. Also our error expressions for the general case of jointly spatio-temporally correlated Rayleigh and Rician fading are new, to the best of our knowledge. We also apply our analysis to some of the more recently developed codes for the MIMO channel, including the super-orthogonal codes and the linear dispersion codes.
