矿震信号处理，福利叶变换，小波包分解，频带能量(Efficient mine microseismic monitoring)

Matlab的Simulink简明教程，简单易学，值得一看(Simulink)

说明：  QPSK解调的 MATLAB 实现 包括原chengxu和仿真(QPSK demodulation of the MATLAB implementation)

有关matlab学习的ppt,内容很全面，希望对大家有点用处(For matlab learning ppt, the content is very comprehensive, I hope we are a bit useless)

matlab code to detect the different ECG features

说明：  该程序是一位同学写的，运行该程序需要rtlSDR设备，便宜一点的淘宝不到100元，插上rtlsdr后，配置好matlab环境，能够实现扫描25M-1.75GHz的当地频谱，当然也可以自行修改范围(rtlsdr rx specsweeep 25MHz~175MHz)

超球体支持向量机是单类支持向量机的一种，超球体OC-SVM算法的思想为寻找一个超球体，使其半径尽可能小的同时，包含的训练样本数尽可能多。(Hypersphere support vector machine is a single-class support vector machine, thought hypersphere OC-SVM algorithm to find a hypersphere, so radius as small as possible while the number of training samples contain as much as possible.)
