[Abstract]:In this paper, the research results of channel capacity of CPM system are summarized, and the capacity analysis method and calculation results of CPM in Rayleigh fading channel are derived. Firstly, the basic concept of CPM system and its finite state Markov model are reviewed, and the method to calculate the reachable information rate of CPM in AWGN channel is discussed. Then it is extended to the Rayleigh fading channel, and an algorithm for calculating the CPM capacity under the channel is derived. Two cases of known channel state information and unknown channel state information are considered. The capacity curves of several typical CPM schemes in AWGN and Rayleigh fading channels are given by Monte Carlo simulation after the derivation of the capacity calculation algorithm.
