Performance Analysis of Space Time Block Coded Systems over Frequency Selective Rayleigh Fading Channels

This paper studies a different approach to the performance analysis of arbitrary Space Time Block Coded over frequency selective Rayleigh fading channels for single carrier (SC) systems. We first analyzed the performance of Space Time Block Code (STBC) systems only, and then, the performance of STBC concatenated with channel codes systems. The pairwise error probability (PEP) is derived for arbitrary STBC over the generalized frequency selective Rayleigh fading channels. The approximation of a bit error probability (BEP) is then computed by using the union bound. The simulation results are also given to verify the analytical performance. It is shown that the theoretical results and the simulation results of the STBC systems are identical for all SNRs.
