摘　　要：以MATLAB GUI为软件开发平台,设计了随机信号的分析与处理系统。该系统以随机信号分析的基本理论和方法为基础,通过对随机信号进行相关性分析和功率谱密度分析,掌握有用信号和噪声信号的频谱特征,设计FIR数字滤波器滤除噪声信号,提取有用信号,完成对随机信号的有效去噪处理。该系统界面设计美观大方,功能设计简捷方便,并易于进一步扩展。实验证明,该系统较好地实现了随机信号的分析与处理。Using MATLAB GUI as software development platform,designs the system of random signal analysis and processing is designed.The system is based upon the basic theory and methods of random signal analysis,analyzes their correlation and power spectral density,masters the spectrum of both useful signal and noise signal,designs the FIR digital filter to remove the noise and extract the useful signal,so effectively completes the random signal denoising.The system is elegant in interface design,easy and simple in functional design and convenient to further expansion.The experiment shows that the system has achieved the random signal analysis and processing better.
