simulink 非线性环节使用的磁滞特性验收程序，有验收结果(simulink link the use of non-linear hysteresis characteristics of the acceptance procedure, has accepted the results of)

说明：  这里介绍了一种基于自适应滤波的噪声抵消法，采用归一化最小均方误差算法，采集实际噪声环境下各种不同信噪比的带噪语音样本进行降噪处理，实验结果表明，处理后信号的信噪比得到了较大程度的提高，大大改善了听音效果，具有很高的可懂度，且语音自然度好，没有失真；并与谱减法进行了比较，自适应噪声抵消法的降噪幅度比谱减法有一定提高，在听音效果上，用自适应噪声抵消法处理后的语音在清晰度，自然度方面优于谱减法。(Here a novel adaptive noise cancellation method using normalized least mean square algorithm, collecting a variety of actual noise environment, the SNR of noisy speech samples for noise reduction, experimental results show that treatment After the signal to noise ratio was greater improvement in the level, greatly improved the listening results, with high intelligibility and naturalness of speech is good, no distortion and were compared with the spectral subtraction, adaptive noise cancellation law than the spectral subtraction noise reduction rate of a certain improvement in the listening results, and with the adaptive noise cancellation method in the treatment of voice clarity, naturalness is better than spectral subtraction.)

本代码是基于MATLAB开发的，主要用于仿真基于PAM调制的UWB发射机(Pam调制的UWB 发射机)

X信号的时域和频域分析，及针对该信号的滤波器设计、验证(X signals in time domain and frequency domain analysis, and for the signal of the filter design, verification)

MATLAB程序，用小波变换的方法实现Haar分解与重构。(MATLAB program, the method used to achieve Haar wavelet transform decomposition and reconstruction.)

in this program we simulate euler angles of a body for example a missile.an omega is given to it and then it calculates sye,phi and teta. it is simple program for beginners in navigation studings.

实现光谱检测中，多个检测点的平均,并进行sg平滑。 注：一点的多个光谱应保存在一个文件夹中，并以数字编号(Implementation of spectrum detection, the average number of detection points, and SG smoothing. Note: multiple spectral point should be kept in a folder, and a digital number)

用SVM进行分类时，需要对原数据进行归一化处理。(When using SVM classification, the need for raw data normalized.)

This program implements equation (2.26) using the waterfilling algorithm

说明：  基于matlab语音短时频谱分析，到谱分析，语谱图分析及结果(Matlab voice-based short-time spectral analysis, the spectral analysis, spectrum analysis and the results of language)
