多进制CPFSK的减少状态格状图

A Reduced-State Trellis for M-ary CPFSK

连续相位调制的最佳相于解调的误码性能取决于其最小平方欧氏距离。本文在不减少其最小平方欧氏距离的前提下，提出了多进制ＣＰＦＳＫ的减少状态格状图，从而减少了维特比的译码复杂度。

The error performance of continuous phase modulation (CPM)with optimal coherent detection depends on its minimum squared Euclidean distance(MSED). In this paper,a reduced-state trellis for M-ary CPFSK is presented under the condition that the MSED is not reduced therefore the complexity of Viterbi decoding is reduced.
