A comprehensive investigation of the impact of nonzero boresight pointing error on the performance of modulating retro-reflector (MRR) free space optical (FSO) communication systems is the goal of this work. In particular, the end-to-end signal-to-noise ratio (SNR) statistical characteristics including probability density function (PDF), cumulative distribution function (CDF), moments as well as moment generating function (MGF) are formulated. Capitalizing on these results, the system average BER and outage probability are derived. Moreover, the asymptotic performances of the system ergodic capacity at low and high SNR values are deduced as well. The obtained expressions are verified via Monte-Carlo simulation.

具有非零视轴指向误差的调制后向反射器 FSO 通信系统的性能

这项工作的目标是全面调查非零视轴指向误差对调制后向反射器 (MRR) 自由空间光 (FSO) 通信系统性能的影响。特别地，制定了端到端的信噪比（SNR）统计特性，包括概率密度函数（PDF）、累积分布函数（CDF）、矩以及矩生成函数（MGF）。利用这些结果，可以导出系统平均 BER 和中断概率。此外，还推导出了系统遍历容量在低和高 SNR 值下的渐近性能。获得的表达式通过蒙特卡罗模拟进行验证。
