LDPC-Coded Optical PPM Communication System over the Atmosphere Turbulence Channels

摘要：

We have studied the PPM signal demodulation method and adopted a simplified method of extracting soft information. On this basis, the LDPC as channel coding code is applied into the atmosphere laser communication system, and LDPC-coded optical PPM system is simulated in the atmosphere turbulence channels with combination of the simplified extracting software information method. The simulation results show that the above program can satisfy the need of atmosphere laser communication system.
