用Blackman-Tukey方法（自相关法）实现对任意输入的实序列函数x(n)作功率谱估计。-Using Blackman-Tukey method (autocorrelation method) to achieve the actual sequence of arbitrary input function x (n) for power spectrum estimation.

基于语音信号处理的matlab 自相关函数 利用这个函数做自相关看起来更加直观-Autocorrelation seems more intuitive use this function to do based on the speech signal processing matlab autocorrelation function
