Iterative Differential PSK Demodulation and Channel Decoding Based on Linear Prediction over Rayleigh Flat Fading Channels

WU Yi,ZHOU Shi dong,YAO Yan (State Key Lab on Microwave & Digital Communications,Tsinghua University,Beijing 100084,China)  
Based on the properties of Rayleigh flat fading channel model in mobile radio communication,we research and propose a kind of new turbo DPSK based on linear prediction of channel gain.The receiver has a simple structure due to the fact that linear prediction here does not depend on the autocorrelation function of the fading process.Moreover,we combine linear prediction with Per survivor processing to improve channel estimation.Simulation result show that new Turbo DPSK system provides good BER performance in fading channel.
