image processing in matlab

说明：  PPC上面类似Matlab的语言环境，希望有pda的同学们喜欢(PPC above language similar to Matlab environment, and hope to have the students like pda)

采用OFDM的数据符号去估计多普勒频率，从而估计出移动台的速度(Data using OFDM symbols to estimate the Doppler frequency, thereby to estimate the speed of the mobile station)

一般支持向量机的回归和分类程序，均可以运行(General support vector machine regression and classification procedures can run)

This matlab code has a PCM siystem

matlab 实现的odfs跟踪算法,功能强大新颖(matlab method)

首先给出了谐波小波时频剖面图检测含噪声信号的微弱奇异成分的方法 然后运用谐波小波时频剖面图方 法分析了碰摩故障仿真信号 最后利用该方法对多个实际汽轮机组动静碰摩故障的真实振动信号进行了分析研 究。结果表明, 谐波小波能够得到其它信号分析方法无法得到的特征, 有效识别机组的碰摩故障。(Harmonic wavelet time􀀁 frequency profile plot is introduced firstly in practice to identify weak singularity in a signal with noise clearly. With this method, emulational signal and vibration data of the rubbing of the large practical turbo-generator units are analyzed successfully, which prove that the method is effectively extract the rubb ing signal feature.)

说明：  在神经网络中用求协方差矩阵的方法对人脸图像进行压缩及恢复(In the neural network covariance matrix using the method of face image compression and restoration)

matlab的优化算法，经典算法，可用于数学建模(matlab optimization algorithm, the classical algorithm can be used for mathematical modeling)

自编matlab小波分解以及重构的函数，希望大家多多指教，后期完善了自编的卷积积分再上传(matlab for wavelet by self)
