摘　　要：本文综合出一种能够分离并解调共道AM/FM信号的系统。导出了单个AM/FM的MAP估计方程,在此基础上构造了带有幅度闭环控制的锁相环路,并给出环路的数学模型。然后推广到双路共道AM/FM信号,得出带有幅度闭环控制的交叉耦合锁相环路及其数学模型。The purpose of this paper is to synthesizing a system, which can separate and demodulate the cochannel AM/FM signal. First based on MAP estimation of a AM/FM signal a phase locked loop with closed amplitude control and its mathematical model arc introduced; then estimating the two cochannel AM/FM signal, a cross-coupled phase locked loop with c-losed amplitude control is obtained.
