摘要
提出基于空间站照明系统的空间可见光通信技术,主要研究采用RAKE接收技术改善可见光通信中出现的由多径效应引起的码间串扰和衰落问题。仿真结果表明,采用RAKE方式的光接收技术不仅可以解决码间串扰,降低误码率,还可以提高系统的输出信噪比。
The visible light communication （VLC） technology based on the lighting system of space station is put forward. This paper mainly studies to improve inter-symbol interference and fading problem caused by multipath effects in VLC system using RAKE receiving technology. The simulation results in this paper indicate that optical receiving technology utilizing RAKE can not only resolve the inter-symbol interference and reduce the bit error rate （BER）, but also improve the signal to noise ratio of the system output.
