| Abstract: | Inter-symbol Interference(ISI) is an important factor that affects the performance of communication system.How to restrain ISI becomes the key to improve the performance of high-speed white LED optical communication system.This paper describes the generating mechanism of inter-symbol interference and its influence on high-speed white LED optical communication system.A discussion of traditional methods against ISI is given and a technology called diversity reception is proposed.The experimental results show that the diversity reception technology can effectively restrain the influence to communication system caused by ISI,the average SNR raised 2dB. |
