Simulation of Interleavers in Turbo-coded Atmospheric Optical Communication Systems

Combining the characteristics of atmospheric channel with the structures of Turbo encoding and decoding,the Simulink model of atmospheric optical communication system based on Turbo codes was created.Basing on it,we use the Simulink in MATLAB,the system performance effects of different interleaver schemes of Turbo codes were simulated and compared by adopting Log-MAP arithmetic.The conclusions which are very valuable for applying the Turbo codes to the real atmospheric optical communication systems are given.
