just for learning.It s too easy to learn(for lerning)

This little package contains a Parzen Neural Network classifier that can classify data between N classes in D dimensions. The classifier is really fast and simple to learn

首先定义一个高斯白噪声，然后在正弦信号中添加白噪声，再对带噪声的正弦信号进行平均值滤波(First, a Gauss white noise is defined, then the white noise is added to the sinusoidal signal, and then the average filtering of the sinusoidal signal with noise is filtered)

说明：  语音增强的谱减法算法实现，要有一个wav格式的声音文件(Spectral subtraction speech enhancement algorithm, there must be a wav sound file format)

数字水印(digitalwatermarking)是一种信息隐藏技术，它的基本思想是在数字图像、音频或视频等数字媒体作品中嵌入秘密信息，以便保护数字作品的版权、证明作品的真实可靠性、跟踪盗版行为或提供作品的附加信息。(Digital Watermarking (digitalwatermarking) is a kind of information hiding technology, its basic idea is in the digital image, audio or video digital media works, such as embedded secret information in order to protect the copyright of digital works to prove that the true reliability of the work, tracking piracy works or provide additional information.)

说明：  个人做的AM调制数字解调simulink仿真模块，大家多交流(The AM modulation personal digital demodulation simulink simulation module, we more exchanges)
