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。 Continuous phase modulation (CPM) technology has excellent power spectral characteristics and continuous constant envelope. However, due to its non-linear nature, synchronization and related reception become a technical bottleneck. By linearly equating the CPM signal, the paper improves the traditional linear signal carrier recovery algorithm and proposes an easy-to-implement synchronization algorithm.
