摘要：
In this study, the authors analyse the impact of spatial correlation on the average bit error-rate (BER) performance of amplify-and-forward cooperative relay networks employing Alamouti orthogonal space-time block coding (OSTBC) over Rayleigh fading channels. Closed-form expressions are derived for the moment generating function of the total signal-to-noise-ratio (SNR). The authors then obtain closed-form expressions for the average BER of the system as well as asymptotic expressions for the average BER at high SNRs. To quantify the effects of antenna correlation on the system performance, numerical results are provided and compared for different cases.
