摘要

在本研究中，利用SIM方案推导了gamma-gamma衰落信道中Alamouti方案的平均误码率(BER)的幂级数表达式。分析表明，Alamouti方案在强湍流条件下可获得37 dB的高信噪比增益，在BER为10−6的无分集条件下，在中等湍流条件下可获得27 dB的高信噪比增益。

Performance analysis of Alamouti scheme in free-space optical communications channel

In this study, the power series expression of the average bit error rate (BER) of the Alamouti scheme is derived in gamma-gamma fading channels using the SIM scheme. According to the analysis, the Alamouti scheme could achieve a high signal-to-noise ratio (SNR) gain of 37 dB in a strong turbulence regime, and also a high SNR gain of 27 dB in a moderate turbulence regime over the no diversity at the BER of 10−6.
