介绍了连续相位调制(CPM)的基本原理,分析了CPM信号Laurent分解的具体过程,给出了维特比分支度量值的实现框图和计算表达式,最后通过计算机进行仿真,得到了CPM的误码率曲线。
The basic principle of continuous phase modulation (CPM) is introduced. The concrete process of Laurent decomposition of CPM signal is analyzed. The block diagram and calculation expression of Viterbi branch metric are given. Finally, the error of CPM is obtained through computer simulation Rate curve.
