In this paper, method for analyzing the trellis of ring convolutional coded continuous phase modulation (CPM) is investigated. The number of states in the trellis reflects the complexity of ring convolutional coded CPM. Match encoding approach is used here to calculate the number of states in the trellis for Viterbi receiver, and some detailed rules are found. Moreover, some ring convolution encoders are listed with optimal performance for different number of states.
