passive Anti-islanding method(PJD)

正确率可以达到98％，利用matlab写成的窄带噪声发生，使用高阶累积量对MPSK信号进行调制识别。( Accuracy can reach 98 , Using matlab written narrowband noise occurs, Using high-order cumulants of MPSK signal modulation recognition.)

用MATLAB实现的单神经元PID算法程序(Using MATLAB to achieve the single neuron PID algorithm procedure)

贝叶斯决策理论常用于模式识别中，这是最常用的一种贝叶斯决策的matlab原程序(Bayesian decision theory commonly used in the pattern recognition, This is the most commonly used a Bayesian decision-making procedures of the original Matlab)

计算关联度，本方法使用的是归一化的方法，和传统的经典关联度计算方法相比较，增加了对各个权重的分析和计算，使结果更加有说服力。(Correlation calculation, this method uses the normalized method, and the traditional classical correlation method compared to an increase of weights of the various analysis and calculations makes the results more convincing.)

自适应滤波器LMS算法（去噪的）自己弄的(LMS adaptive filter algorithm (denoising))

weight trajectories for two different initial conditions an step-size( variance of u, denoted by var_u, can be changed. Also, the values of the step-size, in the variable mu, and the value of the initial weight estimate, in the variable w_init, can be changed.)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

决策树的matlab实现,包含训练和测试(Decision Tree matlab implementation)

希尔伯特黄变换的C语言实现，包括希尔伯特谱分析，瞬时频率的求解等。(Hilbert Huang Transform C language, including Hilbert spectral analysis, such as instantaneous frequency solution.)
