Matlab code for COST207

In this letter, we propose anovel family of windowing technique to compute mel frequency cepstral coefficient (MFCC) for automatic speaker recognition from speech. The proposed method is based on fundamental property of discrete time Fourier transform (DTFT) related to differentiation in frequency domain. Classical windowing scheme such as Hamming window

机器学习算法， 使用Fisher score进行特征选择。(Machine learning algorithms, feature selection using Fisher score.)

说明：  积分分离PID算法的思想是：当被控量与设计的偏差量偏差较大时，取消积分量，以免积分量使系统稳定性降低，超调量增大；当被控值接近定值时，引入积分控制，以消除静差，提高系统精度。(integral separation PID algorithm thinking is this : When the volume charged with the design of larger deviations deviation, the abolition of Integral volume, the volume so integral to reduce the system stability, over-regulation increased; When charged with setting value approach, the introduction of integral control to eliminate static error and improve system accuracy.)

经典谱分析和改进算法，用于估计信号功率谱和方位，(Classical spectral analysis and improved algorithms for estimating the signal power spectrum and the position,)

Optical Simulation with Matlab

说明：  机床时频域信号特征提取，包括均方根值、峰值、峰值因子、峭度因子、脉冲因子、裕度系数、波形因子、功率谱密度、频率方差、均方频率(Eigenvalue extraction)
