In this paper we propose a dual-hop mixed cooperative power line communication (PLC)-visible light communication (VLC) system, in which the VLC system is linked to the PLC backhaul link with the assistance of a decode and forward relay. The performance of the PLC link is evaluated under the effect of log-normal fading, and the link is presumed to be affected by both additive background and impulsive noises. The VLC link's channel characteristics are taken as a function of the position of the end users. The proposed study provides novel closed-form expressions of various statistics of the equivalent end-to-end signal-to-noise ratio of the considered system. Taking these derived entities into account, we also evaluate closed-form expressions of various performance metrics of the proposed system.

室内通信系统混合合作PLC-VLC系统的性能分析

在本文中，我们提出了一种双跳混合合作电力线通信（PLC）-可见光通信（VLC）系统，其中VLC系统在解码和前向中继的帮助下链接到PLC回程链路。在对数正态衰落的影响下评估PLC链路的性能，并假定该链路受累加背景噪声和脉冲噪声的影响。VLC链接的频道特性被视为最终用户位置的函数。拟议的研究提供了所考虑系统的等效端到端信噪比的各种统计数据的新颖封闭形式。考虑到这些派生的实体，我们还评估了所提议系统的各种性能指标的闭式表达式。
