利用CVX进行优化，得到期望加权矢量，从而的得到需要的波束形成(CVX using optimized to give the desired beamforming)

自适应滤波器中的rls和lms两种算法matlab仿真比较程序。(Rls adaptive filter and the LMS algorithm matlab simulation comparison of two procedures.)

基于matlab的小波变换程序，可以方便的进行信号的小波分析。经过验证，可以使用。这里使用的是morlet小波。主要是处理地震数据。(Matlab-based wavelet transform process, you can easily carry out the wavelet analysis of signals. After verification, you can use. Here use morlet wavelet. Processing seismic data.)

Le Gall 5/3 小波变换及其反变换，可用于JPEG2000无损压缩中(Le Gall 5/3 wavelet transform and its inverse transform，which can be used for lossless compression in JPEG2000)

基于小波变换的语音识别，内含毕业论文和摘要以及可执行源程序(Speech recognition based on wavelet transform, containing thesis and summary of executable source code)

余弦变换-DCT。好用的小波变换方法程序。(Cosine transform-DCT. Use of wavelet transform.)

说明：  紧支撑小波基的构造。 以Daubechies小波滤波器系数为例，推导出小波函数及尺度函数，并画出其图像. void Convolution(double* pShortData, int nShort, double* pLongData, int nLong) int CalcScaleFunction(double* pOutData) int CalcWaveletFunction(double* pOutData) Convolution()不是通用的离散卷积代码，而是简单地实现了后面两个函数需要的离散卷积，它要求输入的前一个数组长度小于后一数组长度，而且卷积结果就直接覆盖存储在后一数组中。CalcScaleFunction()计算尺度函数，CalcWaveletFunction()计算小波函数。 (Compactly supported wavelet bases constructed. To Daubechies wavelet filter coefficients as an example, the derived wavelet function and scaling function, and draw their images. Void Convolution (double* pShortData, int nShort, double* pLongData, int nLong) int CalcScaleFunction (double* pOutData) int CalcWaveletFunction ( double* pOutData) Convolution () instead of generic discrete convolution code, but simply the realization of a function behind the need for two discrete convolution, which requires input before an array length is less than the array length of the latter, but the result of convolution directly covered by the latter is stored in the array. CalcScaleFunction () calculated scaling function, CalcWaveletFunction () calculation of wavelet function.)

说明：  利用matalab中的simulink的仿真做的pm的调制与解调 非常的有用(Matalab use of simulation in simulink to do the modulation and demodulation pm very useful)
