Gaussian Mixture Model test

说明：  本程序为利用matlab提供的小波进行图像去噪的简单算法(This procedure provides for the use of wavelet matlab simple algorithm for image denoising)

use a three order loop to track the GPS L2C signal, could be useful for beginner

matlab实现的物体特征提取程序，提取效果不错，(matlab program to achieve the object feature extraction, the extraction well,)

golf 90hp stock engine remapped ecu

考虑饱和凸极补偿的永磁同步电动机转子位置估计(Consider the position of permanent magnet synchronous motor rotor saliency compensation estimated saturation)

说明：  Time Frequency Toolbox matlab时频分析工具箱,里面有各种时频分析函数，用matlab实现的，小波变换，Gabor变化，短时傅里叶变换等等(AF Ambiguity function AR Auto-regressive (filter or model) ASK Amplitude shift keyed signal BJD Born-Jordan distribution BPSK Binary phase shift keyed signal BUD Butterworth distribution CWD Choi-Williams distribution FM Frequency modulation FSK Frequency shift keyed signal GRD Generalized rectangular distribution HT Hough transform MHD Margenau-Hill distribution MHSD Margenau-Hill-Spectrogram distribution MMCE Minimum mean cross-entropy NAF Narrow-band ambiguity function PMHD Pseudo Margenau-Hill distribution PWVD Pseudo Wigner-Ville distribution QPSK Quaternary phase shift keyed signal RID Reduced interference distribution STFT Short-time Fourier transform TFR Time-frequency representation WAF Wide-band ambiguity function WVD Wigner-Ville distribution ZAM Zhao-Atlas-Marks distribution)

说明：  仿真了SC_FDE系统QPSK调制信号通过帧同步，定时同步，载波同步，信道估计和频域均衡之后重新解码的过程，对初学者可能有用(Simulated SC_ FDE system,which QPSK modulation signal is decoded after frame synchronization, timing synchronization, carrier synchronization, channel estimation and frequency-domain equalization. It may be useful for beginners)

对图像进行纹理分析，分几个方向进行的处理。matlab程序(right image texture analysis, in several directions at the moment. Matlab procedures)

就是在matlab环境中模拟炮弹从何点火到射出炮口这段过程中压力形成等的因素(Is artillery shells where the ignition to the injection pressure to form the muzzle during this process simulation in Matlab environment factors)
