【摘要】：針對CPM系統(tǒng)的信道容量研究結果進行了綜述,并推導計算了Rayleigh衰落信道下CPM的容量分析方法與計算結果。首先回顧了CPM系統(tǒng)的基本概念及其有限狀態(tài)馬爾可夫模型,并對AWGN信道下CPM的可達信息速率計算方法進行了討論;然后將其推廣到Rayleigh衰落信道,推導出在該信道下計算CPM容量的算法�？紤]了接收端已知信道狀態(tài)信息及未知信道狀態(tài)信息2種情況。在導出容量計算的算法后,通過Monte Carlo仿真給出了在AWGN及Rayleigh衰落信道下幾種典型CPM方案的容量曲線。
[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.
