| Abstract: | In order to reduce the BER in wireless optical communication,Turbo code is used in the paper.Based on the analysis of the atmospheric channel,Turbo is used to code the channel and modify the system of coding and decoding.Then the system model is built up based on the atmospheric channel.The influence of different iterative times is analyzed.The result shows that the iterative times have enormous effects in Turbo coded system.The research is an important foundation for wireless optical communication system. |
