摘要

随着可见光通信系统研究的不断发展,解决可见光通信上行通信链路缺失的问题日益引起重视。建立双向可见光通信系统,意味着在系统两端的收发器件上需要同时实现光电转换与电光转换。提出了以发光二极管(LED)同时作为光信号收发元件的实时双向可见光通信系统方案,设计了时分复用方式的LED双向工作控制机制,实现了双向可见光通信。在不同的收发端仰角下进行了实时双向通信系统的实验,实测结果表明本系统方案仅以LED作为光收发元件、不需严格对准和中继放大即可实现2 m以上距离、8 Mb/s速率的实时双向可见光通信。

Abstract

With the continuous development of the research in visible light communication system, it is highlight to solve the problem of lacking uplink communication. The bi-directional visible light communication system means that both ends of the system need to realize photoelectric conversion and electro-optical conversion at the same time. In this paper, we propose a real-time bi-directional visible-light communication system scheme with light-emitting diodes (LEDs) as both optical signal transmitter and receiver, in which we design the mechanism of controlling LED bi-directional work by the way of time-division multiplexing to achieve a bi-directional visible light communication. The real-time bi-directional communication system experiments are done under the different elevation angles of transmitter and receiver. The results show that the system scheme can realize real-time bi-directional visible light communication at a distance of more than 2 m and a transmission rate of 8 Mb/s only with LED as optical transmitter and receiver, without strict alignment and relaying amplification.
