瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel (Rayleigh fading channel) is a radio signal propagation environment, the statistical model. The model assumed that after the signal through the wireless channel, the signal amplitude is random, that is, " fading" and subject to its Rayleigh distribution envelope.)

filter wavelet. ECG. search best filter and best families of wavelet.

自己实现的瑞利分布，有很实用的价值，非常适合新手学习 (Rayleigh distribution of their implementation, there are very practical value, ideal for novice learning)

软件无线电在MATLAB下的仿真，包括全套程序，较全，有使用意义(Software Radio in the MATLAB simulation, including a full set of procedures, than the whole, there is the use of significance)

vad（语音活动检测）的matlab代码，采用频域的方法计算信噪比。(vad (voice activity detection) Matlab code, using frequency-domain approach to calculate the signal-to-noise ratio.)

说明：  差分进化程序，有注释，可以直接修改函数运行！(Differential evolutionary process, there are notes, you can directly modify the function to run!)

度量学习，2009年的文章和程序，LMNN,基于最优化方法的度量学习算法(Metric study of article in 2009 and procedures, LMNN, a measure of the optimization method based on learning algorithm)

最经典的人工神经网络教程，内容详细,适用于广大战友(Classic artificial neural network tutorial, detailed and apply to the majority of his comrades)
