摘要

自由空间光学(FSO)是光通信系统中一种较好的信道。自由空间光通信(FSOC)中WDM的实现是为了克服由于雨、雾、霾等大气湍流导致的信号退化或信号丢失。因此，波分复用可以更有效地提高信道容量。采用混合光放大器的波分复用FSOC系统解决了各种大气条件下的信号退化问题。多输入多输出(MIMO)用于减轻湍流对长距离通信的影响，提高了可靠性。本文主要利用Optisystem仿真软件研究了带延迟线滤波器(DLF)的WDM-MIMO系统的最大链路长度，并对链路的眼图、最小误码率和最大q因子等参数进行了分析。

Investigation of WDM-MIMO Channel with DLF in Free Space Optical Communication

Free Space Optics (FSO) is a favourable channel used in optical communication system. WDM in Free Space Optical communication (FSOC) is implemented to overcome the signal degradation or loss of signal due to atmospheric turbulence like rain, fog, haze etc. Therefore, the capacity of the channel can be improved by WDM more efficiently. The WDM based FSOC system using Hybrid Optical Amplifier provides a solution to signal degradation in various atmospheric conditions. Multiple Input Multiple Output (MIMO) is used to mitigate the effect of turbulence for long distance communication with increased reliability. This paper mainly focuses to investigate the maximum link length in WDM-MIMO system with Delay Line Filter (DLF) using Optisystem simulation software and the link parameters such as Eye Pattern, Minimum BER and Maximum Q-factor are analysed.
