Abstract :
Insightful closed-form formulas for the exact pairwise error probability (PEP) of quasi-orthogonal space-time block codes in Rayleigh fading channels are presented. In addition, simple asymptotic expressions are proposed, from which the achievable asymptotic diversity orders are easily determined in the high signal-to-noise ratio regime. Finally, comparing analytical and simulation results, the accuracy of the derived analytical formulas is validated.
