【Abstract】 In order to reduce the access time of wireless laser communication users and enhance the utilization rate of channels, a parallel channel equalization method at the receiving end of wireless laser communication under multipath interference is proposed. Firstly, the preprocessing of wireless laser communication signal filtering is performed, and the signal is denoised by the filter to ensure the quality of the signal, and at the same time, it is normalized to facilitate the equalization of the channel. Secondly, the communication channel under multipath interference is estimated, and the parallel concept is added on the basis of the channel estimation result to obtain the channel equalization processing result, and realize the parallel equalization of the wireless laser communication receiving end channel. The experimental results show that the proposed method has strong anti-interference performance, better channel equalization performance, and faster channel estimation speed, with an average channel estimation speed of 1.96 m/s.更多还原
