A REDUCED-STATE TRELLIS FOR FULL RESPONSE CPM
全响应CPM的减少状态格状图

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.
