Abstract

Currently, a new statistical model named málaga or $\mathcal{M}$-distribution was proposed to model the atmospheric turbulence channel. All existing traditional statistical channel models can be derived from this. Atmospheric turbulence degrades the performance of a free space optical communication (FSO) system. Spatial diversity is a promising technique to enhance the performance of the system. In this article, an FSO system is analyzed with spatial diversity with on-off keying modulation over $\mathcal{M}$-distributed turbulent channel. A novel closed-form expression for bit error rate is derived for the proposed FSO systems over this channel and analyzed the effects of pointing errors.
$\mathcal{M}$-分布式衰落信道下MIMO FSO通信系统性能分析
目前,提出了一种新的统计模型málaga或$\mathcal{M}$-distribution来模拟大气湍流通道。所有现有的传统统计渠道模型都可以由此导出。大气湍流会降低自由空间光通信系统的性能。空间分集是一种很有前途的提高系统性能的技术。本文分析了在$\mathcal{M}$-分布湍流信道上具有开关键控调制的空间分集的FSO系统。推导了该信道上的FSO系统误码率的封闭表达式,并分析了指向误差对误码率的影响。
