ABSTRACT The research area of optical wireless communication links has attracted significant interest over the last years due to the significant advantages offered by this kind of technology. However, the performance of FSO communication systems depends strongly on the effects, which are related to the atmosphere along the propagation path such FSO links are using. More specifically, the weather conditions and atmospheric turbulence effects can deteriorate considerably the performance characteristics. In this work, we are studying the joint influence of atmospheric turbulence and time jitter effects on the average BER of an FSO link by presenting a new approach for various modulation schemes. Thus new closed-form mathematical expressions are derived for accurate estimation of the BER performance of the optical wireless communication systems. Finally, using the obtained expressions and typical parameter values for FSO links, the numerical results are presented and then verified through Monte Carlo simulations.

时间抖动对具有各种调制方案的伽马-伽马湍流 FSO 链路性能的影响

摘要 由于这种技术提供的显着优势，光无线通信链路的研究领域在过去几年引起了极大的兴趣。然而，FSO 通信系统的性能在很大程度上取决于影响，这些影响与沿此类 FSO 链路使用的传播路径的大气有关。更具体地说，天气条件和大气湍流效应会显着降低性能特性。在这项工作中，我们通过提出一种适用于各种调制方案的新方法来研究大气湍流和时间抖动效应对 FSO 链路平均 BER 的共同影响。因此，推导出了新的封闭形式的数学表达式，用于准确估计光无线通信系统的 BER 性能。
