Paper Abstract

This paper proposes a new method for variable rate DPSK in the satellite-to-ground laser communication. Compared to the general method, this method doesn’t need to change the original communication rate, reduces the complexity of the system. In theory, SNR can improve above 3 dB when rate into half. We construct a simplified experimental apparatus to verify the effectiveness of the proposed method. The experimental devices and results are presented. Offline processing results are very similar to theory, is superior to the traditional means. The further study about doppler effect and clock synchronization is being conducted.
