基于BPSK的光无线通信系统的信道容量分析

Analysis for channel capacity of BPSK-based optical wireless communication system

从香农的信息论出发,在用Γ模型分析扰动强度分布的基础上,利用蒙特卡罗积分法计算了基于BPSK的光无线通信系统的信道容量,详细分析了几种不同扰动强度下信道容量和信噪比的关系,为设计光无线通信系统提供了重要的理论基础。

The atmospheric turbulence intensity is analyzed by the Г model based on the theory of information, and the channel capacity of optical wireless communication system based BPSK is calculated by Monte Carlo integral, the detailed analysis of the channel capacity versus the signal-noise-rate（SNR） in different turbulence intensity is given, it is a key theoretical basis for the designs of optical wireless communication.
