application of personal identification.

SVM(支持向量机)，二分类，多分类，多分类一对一，多分类一对多训练及测试matlab代码(SVM two classes muticlasses mutioneagainstone mutioneagainstall matlab code)

在小波分析及其变换中，Hurst指数的Matlab实现(Wavelet analysis and transformation, Hurst exponent of Matlab achieve)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)

这是一个非常好的关于OFDM的英文文章，它是国外的博士论文，对于想了解整个OFDM的朋友来说，可以了解到许多中文文章所没有的知识。(This is a very good article in English on OFDM, which is the doctoral thesis abroad, who want to understand the overall OFDM' s friends, you can understand that many Chinese do not have knowledge of the article.)

说明：  removal of 50 hz noise (power line interference) from ecg signal using adaptive filtering

说明：  维纳滤波器经典代码，加了详细标注，更适合阅读和改进。(Wiener filter classic code, add the detailed mark, more suitable for reading and improvement. )
