| 摘 要： | 根据全响应连续相位调制信号在不同调制指数下的基带循环谱,由数字调制信号的基带循环谱与带通循环谱的关系式,推导了其相应带通信号循环谱的表达式并进行了详细的分析,得出了不同调制指数下循环频率与载频、峰值频偏以及码元宽度之间的关系式.仿真实验证明这些结论是正确的.

| Abstract: | The general cyclic spectral representations of the full response continuous phase modulation(FR-CPM) are developed and analyzed in detail based on the analytic expression of the corresponding base-band cyclic spectra.The relation of the cyclic frequency with the carrier frequency,symbol period,and peak frequency deviation is obtained within the different modulation indexes.These conclusions are proved by the computer simulations. |
