摘要：

This paper introduces the characteristics of wireless channel fading, and uses the model of Rayleigh fading channel to simulate the sea wireless channel. Using Turbo codes as the encoding and decoding scheme of sea wireless communication system. Introducing two kinds of encoding algorithm of Turbo codes, and put forward the method of re-encoding aiming to improve the performance of MAP decoding of Turbo codes. The re-encoding algorithm of Turbo codes will be applied to the channel codec of sea wireless communication system. Finally, we implement the new turbo encoding and decoding algorithms on DSP. Simulation shows that re-encoding method can significantly improve the MAP decoding performance.
