一维信号的小波分解和重构，利用小波变换对一维声音信号进行分解和重构(One-dimensional signal wavelet decomposition and reconstruction, using wavelet transform one-dimensional sound signal decomposition and reconstruction)

说明：  对一个16元等距线阵，间距为半个波长，空间5个相互独立信源从不 同方向入射，信噪比分别为30、25、20、15、5dB。采用MUSIC方法估 计其空间入射方向(For a 16 element equidistant linear array, the spacing is half a wavelength, and five independent sources are incident from different directions. The SNR is 30, 25, 20, 15 and 5dB respectively. Music method is used to estimate the spatial incident direction)

matlab知识聚集，方便快捷的学习知识，一款非常实用的软件(Matlab knowledge aggregation, convenient and quick learning knowledge, a very practical software)

维纳滤波，能滤除干扰噪声，提取有用信号。但是当输入信号的统计特性偏离设计条件，它就不再是最佳的了，这在实际应用中受到了限制。 (Wiener filter, to filter out interference noise, extract the useful signal. However, when the statistical characteristics of the input signal deviates from the design conditions, it is no longer optimal, which has been limited in practical application.)
