Abstract

recently, Free Space Optical (FSO) communication has been evaluated in indoor and outdoor experimental environments for other communication applications, which opens the study of environmental effects in FSO communications, these effects represents the nature environments around us such as rain and fog, which are termed by mathematical distribution models such as Iognormal and Gamma-gamma distribution. One of the major solutions that proposed to reduce these effects and enhance the received signal is the use of Multiple Input Multiple Output MIMO diversity techniques in FSO which is also considered in this study in addition to Gamma-Gamma turbulence channel. In this paper, a simulation based study is performed to evaluate Free Space Optics Communication FSOC which represents the latest technologies that implies the highest data rate links which is been used in more sensitive communication fields such as satellite communications. The results obtained from Matlab modeling. Simulations showed that better received signal can be achieved.

基于分集技术的伽马湍流信道MIMO FSO通信性能评估

近年来，自由空间光学(FSO)通信在室内和室外实验环境中进行了其他通信应用的评估，从而开启了对FSO通信中环境效应的研究，这些影响代表了我们周围的自然环境，如雨和雾，这些影响被称为数学分布模型，如ognormal和Gamma-gamma分布。提出减少这些影响和增强接收信号的主要解决方案之一是在FSO中使用多输入多输出MIMO分集技术，除了Gamma-Gamma湍流信道外，本研究还考虑了该技术。本文对自由空间光通信FSOC进行了仿真研究，该FSOC代表了最新的技术，意味着最高的数据速率链路，已用于更敏感的通信领域，如卫星通信。结果通过Matlab建模得到。仿真结果表明，该方法可以获得较好的接收信号。
