论文摘要
在本文中，我们研究了光学无线中继器，作为发射器与用户之间的继电器终端（红外光无线通信（IROWC）系统）。引入了一种延迟适应方法来解决不同继电器终端的不规则信号到达时间的问题。使用拟议的延迟适应方法，在典型的两相IROWC系统中研究了三种不同的继电器终端部署方案。模拟结果表明，与常规系统相比，所提出的系统具有更好的脉冲响应，并且使用延迟适应方法的继电器系统的根平方延迟扩散平均比常规系统少30％。
In this paper, we investigate optical wireless repeaters as relay terminals between a transmitter and a user in an Infrared Optical Wireless Communication (IROWC) system. A delay adaptation method is introduced to solve the problem of irregular signal arrival time from different relay terminals. Three different relay terminal deployment scenarios were investigated in a typical two-phase relay IROWC system with the proposed delay adaptation method. The simulation results indicate that the proposed system has better impulse response compared to the conventional system and that the root-mean-square delay spread of the relay system with the delay adaptation method is on average 30% less than the conventional system.
