摘要:

在本文中,我们研究的光无线中继器之间的发射机和用户的红外光无线通信(IROWC)系统的中继终端。针对不同中继终端信号到达时间不一致的问题,提出了一种时延自适应方法。在典型的两阶段中继IROWC系统中,三种不同的中继终端部署方案进行了研究,提出的延迟自适应方法。仿真结果表明,与传统系统相比,该系统具有更好的脉冲响应,采用时延自适应方法的中继系统的均方根时延扩展平均比传统系统小30%。

英文摘要:

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.
