说明：  这是语音信号处理里面的，基本谱减法，处理的效果很不错，很适合初学者研究！(This is the speech signal processing inside the basic spectral subtraction to deal with the effect of very good, very suitable for beginners study!)

使用k均值法对一组数据进行聚类，画出结果图像(Use the k-means clustering, a set of data to draw the resulting image)

In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. The name spread spectrum comes from the fact that the carrier signals occur over the full bandwidth (spectrum) of a device s transmitting frequency.
