pp波和ps波反射系数 pp-ps-wave

In this program we demonstrate the MP, OMP, WMP, and Thresh algorithm, by running them on a set of test signals and checking wether they provide the desired outcome

In this code we use the technique of keyword spotting to search in the spoken document

卡尔曼滤波灰色理论在变形监测中的预测预报(Calman filter grey theory in prediction of deformation monitoring)

说明：  使用小波算法对语音信号进行降噪处理，里面包含三种方法，可以对比(Wavelet algorithm is used to denoise speech signal. There are three methods in it, which can be compared.)

说明：  匹配追踪MP算法，实现信号稀疏分解，运用的是投影思想(Matching up MP to achieve sparse signal decomposition)

独立成分分析算法降低原始数据噪声，实现串口的数据采集，使用混沌与分形分析的例程，包含位置式PID算法、积分分离式PID，车牌识别定位程序的部分功能，用于建立主成分分析模型，在matlab R2009b调试通过。( Independent component analysis algorithm reduces the raw data noise, Achieve serial data acquisition, Use Chaos and fractal analysis routines, It contains positional PID algorithm, integral separate PID, Part of the license plate recognition locator feature, Principal component analysis model for establishing, In matlab R2009b debugging through.)

说明：  计算小波能量熵，简洁明了，实测有效，只需要自己确定小波基函数与分解层数(Calculation of wavelet energy entropy)

说明：  扩频程序，毕业设计时编写的，很好用。MATLAB程序，可以直接调用(Spread spectrum program, written when graduation project, very easy to use)

说明：  二阶巴特沃斯(Butterworth)低通滤波器(Low pass filter)
