摘　　要：本文介绍一种基于单片机控制的无线语音保密通信系统,该系统采用一种新的混沌脉冲宽度调制方式,将数字信息隐藏在脉冲的宽度之中,实现语音信号的无线保密通信。对仿真结果、实验波形进行了分析,详细讨论了该通信系统的同步问题。A wireless audio signal secure communication system based on single-chip computer is introduced. In the proposed system, audio signal wireless secure communication is implemented in a new way of chaotic pulse width modulation,in which data information is represented in the width of pulses. Based on the analysis of simulation results and experiment waveforms, the synchronization of the communication systems is discussed in detail.

关 键 词：混沌脉冲宽度调制(CPWM) Dead-Beat同步 无线通信
