一种新颖的CPM信号接收技术

以8CPFSK为例对连续相位调制（CPM）信号的同步技术和解调技术进行研究，并提出一种新颖的解调和同步联合的接收方案。该方案利用了“多符号差分检测”和CPM信号特有的相位特性，反馈地修正同步误差。仿真结果表明使用该方案不但能简便准确地同步信号接收。而且能大幅度提高连续相位调制信号的误码性能。

A novel receiving technology for CPM signals

This paper takes 8CPFSK as an example to research the timing and demodulation technology for CPM signals receiving and proposes a timing and demodulation combined scheme to receive the CPM signals.The proposed scheme takes the advantage of phase information obtained by "Multiple Differential Detection" and the direct proportion between phase error and timing deviation to correct the deviation of timing.Simulation results illustrate that the proposed CPM receiving scheme not only can give accurate timing with ease,but also can greatly improve the BER performance of the system.
