Abstract

This paper presents a different approach to analyze the performance of an arbitrary linear STBC system over frequency-selective generalized Rician fading channels with single carrier transmissions. First, the performance of STBC without channel coding over ISI Rician fading channels is analyzed. Then, the performance of channel-coded STBC systmes over ISI channels is analyzed. In the analyses, pairwise error probability (PEP) and bit error probability (BEP) are derived and approximated. The approximation of the BEP is computed by using the union bound. Extensive simulation and numerical results are provided to verify the theoretical performance analyses. It is shown that the theoretical analyses and simulation results agree with one another well even at low SNRs.
