论文摘要
本文介绍了对不对称继电器系统的分析,该系统提供了混合室外子系统和室内可见光通信(VLC)接入点之间的通信。室外子系统代表了介绍的混合射频(RF)/自由空间光学(FSO)系统,以减少天气条件对传输质量的影响。封闭形式的中断概率分析表达得出。通过蒙特卡洛模拟给出并确认数值结果。研究并讨论了系统和通道参数对停电概率性能的影响。 VLC子系统的更大光学传输能力在更好的系统性能以及较低的室内环境高度方面反映出。当室内室较高时,光信号的传播更长,并且会有更大的功率耗散和性能恶化。此外,注意到中断概率地板,这是继电器系统设计的重要限制因素。
This paper presents an analysis of the asymmetric relaying system which provides communication between hybrid outdoor sub-system and indoor visible light communications (VLC) access points. The outdoor sub-system represents a hybrid radio-frequency (RF)/free-space optical (FSO) system, introduced to reduce the impact of weather conditions on transmission quality. Closed-form outage probability analytical expression is derived. Numerical results are presented and confirmed by Monte Carlo simulations. The effects of system and channel parameters on the outage probability performance are investigated and discussed. Greater optical transmitted power of the VLC subsystem reflects in better system performance, as well as lower indoor environment height. When the indoor room is higher, the propagation of the optical signal is longer, and there will be greater power dissipation and performance deterioration. In addition, the outage probability floor is noticed, which is important limiting factor for relaying system design.
