摘要

基于海洋湍流衰落环境，考虑一个由广义伽马分布（generalized Gamma distribution，GGD）海洋湍流效应、零视轴指向误差以及路径损耗组成的混合衰落信道模型。利用Meijer-G函数推导出该模型下采用选择式合并（selection combining，SC）下的单输入多输出（single input multiple output，SIMO）-水下无线光通信（underwater wireless optical communication，UWOC）系统下的平均误码率，通过蒙特卡洛仿真验证准确性。仿真结果表明：SIMO系统中SC的性能优于SISO系统的性能；相同平均误码率下，SIMO系统的传输距离也优于SISO系统的传输距离。

Abstract

In the marine turbulence fading environment

a hybrid fading channel model was considered

which included the effects of generalized Gamma distribution (GGD) marine turbulence

zero-mean axis pointing errors

and path loss. Using the Meijer-G function

the average bit error rate for a single-input multiple-output (SIMO) underwater wireless optical communication (UWOC) system employing selection combining (SC) was derived. Finally

the accuracy of the derived expression was validated through Monte Carlo simulations. The results show that the performance of SC in the SIMO system outperforms that of the SISO system. Additionally

for the same average bit error rate

the transmission distance of the SIMO system is also superior to that of the SISO system.
