摘　　要：目前有关循环平稳信号分离的研究工作主要以理论分析和计算仿真为主,为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硬件实验平台系统。采用DSP实现自适应频移滤波器对信号进行处理,利用循环平稳算法实现频谱重叠信号的分离,使用BorlandDelphi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,DSP系统经实验测试,能够实时地实现频谱重叠信号的分离。The research of separating cyclostationary signals is only analysis and validated by simulation. In order to validate the theory of separating cyclostationary signals from spectrally overlapping interference and research how to use the theory in practice, we construct experimental platform for separating cyclostationary signals from spectrally overlapping interference using the cyclostationary of signals with DSP as core of system. We implement self-adapting frequency-shift filter with DSP for separating eyclostationary signals from spectrally overlapping interference and design application using Borland Delphi for user and design communication protocol for serial port communication between DSP system and application. Interface of application is amity, and the experimental results show that DSP system can implement function of separating eyelostationary signals from speetrally overlapping interference.
