摘要

本文研究了解码转发（Decode-and-Forward，DF）方案下的混合射频/水下无线光通信（Radio Frequency-Underwater Wireless Optical Communication，RF-UWOC）系统的性能，其中RF链路服从广义K（Generalized-K，GK）衰落，UWOC链路服从混合指数-广义Gamma（Exponential-Generalized Gamma，EGG）衰落且存在指向误差.针对该混合RF-UWOC系统，推导了信噪比（Signal-to-Noise Ratio，SNR）的累积分布函数（Cumulative Distribution Function，CDF）和概率密度函数（Probability Density Function，PDF）.利用这些结果，推导出了混合RF-UWOC系统的中断概率、平均误码率和平均信道容量的精确表达式.此外，为了获得更多显性结果，还给出了高信噪比情况下中断概率和平均误码率的渐近分析.最后，通过蒙特卡洛仿真，验证了分析结果的准确性.

Abstract

This paper investigates the performance of a mixed radio frequency/underwater wireless optical communication(RF-UWOC) system with decode-and-forward(DF) relay

where the RF link experiences generalized-K fading and the UWOC link is modeled by the mixture exponential-generalized Gamma(EGG) fading with pointing errors. For this mixed RF-UWOC system

we derive the cumulative distribution function(CDF) and probability density function(PDF) of the signal-to-noise ratio(SNR). Based on these results

exact analytical expressions of the outage probability

average bit error rate(BER)

and average channel capacity for the mixed RF-UWOC system are presented. In order to obtain more useful insights

we provide the asymptotic results of the outage probability and average BER in the high SNR regime. Finally

our analytical results are verified via Monte-Carlo simulation.
