Abstract

In this paper, performance analysis of free space optical (FSO) system operating in conditions of strong atmospheric turbulence over Gamma–Chi-square turbulence model, has been carried out. We have observed reception over multi-pulse pulse-position (MPPM) modulation format for the case of strong atmospheric turbulence conditions modeled with Gamma–Chi-square turbulence model and have compared it with turbulence modeling distributions such are: Gamma–Gamma distribution, K-distribution, negative exponential distribution, log–normal distribution. First, we have provided closed-form analytical expressions for average bit error rate (ABER) at the reception for each observed case and then based on them, we have obtained numerical and Monte Carlo simulation results in order to observe turbulence level impact on system performance.

伽玛卡方强大气湍流条件下MPPM FSO传输性能分析

本文利用伽玛-卡方湍流模型对自由空间光学系统在强大气湍流条件下的性能进行了分析。我们观察了用伽玛卡方湍流模型模拟的强大气湍流条件下的多脉冲脉冲位置(MPPM)调制格式的接收情况，并将其与湍流模型分布进行了比较，这些分布包括:伽玛分布、k分布、负指数分布、对数正态分布。首先，我们给出了每个观测情况下接收端的平均误码率(ABER)的封闭解析表达式，然后基于它们，我们得到了数值和蒙特卡罗模拟结果，以观察湍流水平对系统性能的影响。
