摘　　要：本文在文献 [1 ]的基础上提出一种频率漂移下的Viterbi算法 ,研究表明该算法性能良好 ,高信噪比时甚至接近最佳解码性能 .A new Viterbi algorithm for frequency shifted DPSK signals with convolutional encoding based on [1] is proposed.Very attractive performance is obtained and it is shown that the performance of new algorithm approaches to that of optimum Viterbi algorithm with coherent detection as the SNR increases.

关 键 词：频率漂移 VITERBI算法 PSP原则 Dataaided相位估计
