对给定的含噪脉冲信号进行相关检测。检测结果用1、0表示。要求从文本文件中读入数据，分析滤波前后的信号统计特征：包括均值、方差、自相关和功率谱。设计参考信号，进行相关处理和检测；画出原始数据的曲线以及相关结果的曲线(For a given pulse signal associated with noise detection. Test results with 1,0 said. Asked to read from a text file into the data, analyze the demographic characteristics of the signal after filtering include: mean, variance, autocorrelation and power spectrum. Design reference signal, the associated processing and testing draw the curve of the original data and the associated results of the curve)
