【摘要】:针对CPM系统的信道容量研究结果进行了综述,并推导计算了Rayleigh衰落信道下CPM的容量分析方法与计算结果。首先回顾了CPM系统的基本概念及其有限状态马尔可夫模型,并对AWGN信道下CPM的可达信息速率计算方法进行了讨论;然后将其推广到Rayleigh衰落信道,推导出在该信道下计算CPM容量的算法。考虑了接收端已知信道状态信息及未知信道状态信息2种情况。在导出容量计算的算法后,通过Monte Carlo仿真给出了在AWGN及Rayleigh衰落信道下几种典型CPM方案的容量曲线。
[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.
