| 摘 要： | 连续相位调制(CPM)技术具有优良的功率频谱特性和连续恒包络。但是由于其非线性特性,同步和相关接收成为技术瓶颈。文章通过对CPM信号进行线性等效,改进了传统线性信号载波恢复算法,提出了一种易于实现的同步算法,并进行了仿真。

| Abstract: | Continuous phase modulation(CPM) signals present excellent spectra and power efficiency,with no hop in frequency but constant envelope.But with its nonlinearity,the synchronization and detector are too complex to implement.The Laurent representation was adopted to make the CPM signals linear,and the classical linear synchronization algorithm was improved to bear one that suits the CPM case.Computer simulations of the proposed algorithm were also provided. |
