Abstract
Measuring performance of an optical communication system includes reliability and validity indicators.Inter-symbol Interference (ISI) is an important factor that affects the performance of communication system.Channel equalization algorithm is one of the key technology of High-speed visible light communication system,it can effectively eliminate the inter-carrier interference (ICI) and the inter-symbol interference (ISI).A method based on OFDM channel equalization algorithm of High-speed visible light LED communication system is studied in this paper.Simulation results showed that the algorithm reduces the MMSE(mean square-error value) and BER(bit error ratio) as compared with the traditional algorithm,also to some extent,a good optimization of the performance of the transceiver signals can be received in the system.关键词
