摘要

自由空间光通信(FSO)以其低截获概率和抗干扰特性提供了安全的无线通信。本文用提出的Gamma指数信道模型分析了多输入多输出(MIMO) FSO系统的性能。影响FSO系统性能的主要因素是大气湍流。用伽玛指数信道模型描述了在大气信道上的误差性能。推导了采用广义多用户调度(GMS)的MIMO- FSO系统伽马指数信道的PDF。利用子载波正交调幅(SCQAM)，从折射率结构参数和链路距离等方面分析了FSO信道的误码率性能。对该系统进行了分析，并与单输入单输出(SISO) FSO系统和单输入多输出(SIMO) FSO系统进行了性能比较。

MIMO FSO system using Gamma-Exponential channel model

Free Space Optical communication ( FSO) provides secure wireless communication, because of its lowest probability of intercept and antijam characteristics. This paper analyzes the performance of Multiple Input Multiple Output (MIMO) FSO system with proposed Gamma Exponential channel model. Major factor that affects the performance of FSO system is atmospheric turbulence. The error performance over atmospheric channel is described by Gamma Exponential channel model. The PDF of Gamma Exponential channel with MIMO- FSO system using Generalised Multiuser Scheduling (GMS) is derived. With Sub Carrier Quadrature Amplitude Modulation (SCQAM), the BER performance over FSO channel is analyzed in terms of refractive index structure parameter and link distance. The proposed system is analyzed and its performance is compared with Single Input Single Output (SISO) FSO system and Single Input Multiple Output (SIMO) FSO system.
