摘要

在这项工作中，我们分析了基于解码和转发(DF)的双跳自由空间光(FSO)网络在k分布的大气湍流和失调误差(ME)的综合影响下，利用m阶差分相移键控(DPSK)信号的性能。对于考虑的差分双跳FSO网络，我们导出了平均误码率(SER)和中断概率(OP)的封闭表达式。为了解析地得到分集阶，我们还进行了渐近中断分析。此外，我们还利用功率分配参数研究了不同功率分配方案对SER和OP的影响。仿真结果验证了推导出的分析结果。

Differential Transmission over Strong fading Dual-Hop FSO links with Misalignment

In this work, we analyze the performance of decode-and-forward (DF) based dual hop free space optical (FSO) network utilizing M-ary differential phase shift keying (DPSK) signals under the combined impact of K-distributed atmospheric turbulence and misalignment error (ME). For the considered differential dual-hop FSO network, we derive the closed form expression for the average symbol error rate (SER) and outage probability (OP). We also perform the asymptotic outage analysis in order to obtain the diversity order analytically. Further, we also investigate the effect of different power allocation schemes on SER and OP by utilizing power distribution parameter. The simulation results validate all the derived analytical results.
