Abstract :
The exact expression of pairwise error probabilities (PEP) for space-time orthogonal codes is derived for spatially and temporally correlated Rayleigh fading channels in this research. We adopt a moment generating function approach in developing a unified framework to facilitate the evaluation of PEP for various types of channel correlations. Under this new framework, the complexity for evaluating PEP is greatly simplified. Moreover, the simple expression provides valuable insights into the performance of space-time codes in the presence of correlated fading channels.
