摘要

本文研究了负指数大气湍流环境下DPSK副载波强度调制(SIM)自由空间光链路。为了减轻闪烁效应，接收机采用了选择组合空间分集方案(SelC)。分析了使用和不使用SelC空间分集时的误码率(BER)，结果表明，当误码率为10-6时，使用四个独立的pin光电探测器，可以实现不小于38 dB的分集增益。

BER performance of DPSK subcarrier modulated free space optics in fully developed speckle

In this paper a DPSK subcarrier intensity modulated (SIM) free space optical (FSO) link is considered in negative exponential atmospheric turbulence environment. To mitigate the scintillation effect the selection combining spatial diversity scheme (SelC) is employed at the receiver. Bit error rate (BER) analysis is presented with and without SelC spatial diversity, and it is shown that at BER of 10-6 using four independent PIN-photodetectors, a diversity gain of not less than 38 dB is achievable.
