摘　　要：介绍了为验证频谱重叠信号分离的循环平稳算法理论的正确性和进一步研究该理论的实际应用,采用可编程数字信号处理器(DSP)为核心,构建利用循环平稳特性分离平谱重叠信号的实验平台系统。采用DSP实现自适应频移滤波器对信号进行处理,实现频谱重叠信号的分离;使用Borland Delphi开发应用程序,方便用户对参数的设置。该系统应用程序响应速度快、主机用户界面友好,经实验测试,DSP系统能够实时地实现频谱重叠信号的分离。In order to validate the theory of separating cyclostationary signals from spectrally overlapping interference and research how to use this theory in practice, the authors constructed an experimental platform for separating cyclostationary signals from spectrally overlapping interference using the cyclostationary Of signals with DSP as core of the system. It implements self-adapting frequency-shift filter with DSP for separating cyclostationary signals from spectrally overlapping interference and using Borland Delphi for user and design communication protocol for serial port communication between DSP system and application. The interface of application is friendly, and the experimental results show that DSP system can implement function of separating cyclostationary signals from spectrally overlapping interference.
