非协作mCPM信号调制识别与解调算法研究与实现

The Modulation Type Recognition and Blind Demodulation of mCPM Signals in Non-Cooperative Communication

提出一种非协作通信中CPM信号调制类型盲识别算法,利用调制指数、符号率和频偏对调制类型进行联合估计.在此基础上,根据mCPM信号的差分相位,完成了CPM信号的盲解调.理论分析与实际数据实验表明,新方法具有较高的调制类型正确估计概率,且达到了较好的解调效果.

A new method was proposed for the modulation type recognition of continuous phase modulation （CPM） in non-cooperative communication. In the developed framework, the modulation index, the symbol rate and the frequency offset were used to joint estimate the modulation type. On this basis, the blind demodulation was done according to the differential phase. The theory analysis and experimental results indicate that the proposed scheme can achieve a high discrimination of modulation type and results in blind demodulation.
