全响应CPM的减少状态格状图
A REDUCED-STATE TRELLIS FOR FULL RESPONSE CPM
-
摘要: 连续相位调制(CPM)的最佳相干解调的译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,提出了全响应CPM的减少状态格状图,从而减少了Viterbi的译码复杂度。Abstract: The error performance of continuous phase modulation (CPM) with optimal coherent detection depends on the minimum squared Euclidean distance (MSED). In this paper, a reduced-state trellis for full response CPM is presented under the condition that the MSED is not reduced, and therefore the complexity of the Viterbi decoding is reduced.
