In this paper, the performance of the variable weight multiple pulse-position modulation (MPPM) coding technique in an atmospheric optical communication environment under gamma-gamma optical scintillation is analyzed, proposing a closed-form expression for the average bit error rate (BER). This study is based on a hyperexponential fitting of the conditional BER in absence of turbulence fluctuations, leading to closed-form expressions that characterize the behavior of this nonlinear coding scheme. Finally, conditional and average BER expressions proposed here are corroborated with Monte Carlo simulations results.
本文分析了在伽马-伽马光闪烁条件下，大气光通信环境中变权重多脉冲位置调制（MPPM）编码技术的性能，提出了一种平均误码率（BER）的闭式表达式。本研究基于无湍流波动条件下条件 BER 的超指数拟合，得到了表征该非线性编码方案行为的闭式表达式。最后，本文提出的条件和平均 BER 表达式与蒙特卡罗模拟结果进行了验证。
