Abstract:

Three approximate methods (called as scaling, rectangle and trapezia methods respectively) for performance analysis of orthogonal space-time block code (OSTBC) with M-ary phase shift keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) over flat Rayleigh fading channels are proposed, and their approximate performance expressions are given. The analysis of approximate results shows that OSTBC can obtain full diversity orders. The simulation proves that trapezai method is the best of them. When the segments for trapezia method become very small, the approximate performance curves perfectly agree with the theoretical curves. Under high signal to noise ratio , all approximate curves based on the three methods approach to the exact performance curves, and thus satisfy practical engineering requirements.

Key words: orthogonal space-time block, diversity gain, performance analysis
