Precise modeling of the optical channels with different conditions of atmospheric turbulence is an important prerequisite for analyzing the performance of Free Space Optical (FSO) communication systems. Statistical models which have been proposed to describe the optical channels, have some limitations to precisely model the channel. In this paper, The ℳ distribution which is a relatively new and comprehensive model, introduced by the University of Malaga, has been used to model and evaluate FSO/RF hybrid systems under the effect of atmospheric turbulence of the channels for two modes of operation, classic adaptive rate transmission, and the combination of adaptive rate transmission and automatic repeat request.The simulation results have been compared with the experimental results which have been reported by other researchers. It seems, using ℳ distribution model, yields more consistency between design objectives and implementation results.

在湍流通道中使用 Málaga-ℳ 分布模型分析自适应多速率 FSO/RF 混合系统

对不同大气湍流条件下的光通道进行精确建模是分析自由空间光 (FSO) 通信系统性能的重要前提。已经提出来描述光信道的统计模型在精确建模信道方面存在一些局限性。在本文中，马拉加大学引入的 ℳ 分布是一种相对较新的综合模型，已用于对两种运行模式下通道大气湍流影响下的 FSO/RF 混合系统进行建模和评估，经典的自适应速率传输，以及自适应速率传输和自动重复请求的结合。仿真结果与其他研究人员报告的实验结果进行了比较。它似乎，
