anding zhu的较好的数字预失真（DPD）文章(anding zhu' s better digital pre-distortion (DPD) articles)

用matlab对对象进行了模糊PID的编程。(The fuzzy PID programming on object using matlab and VC language. )

matlab程序中图形和图像的处理，pdf格式。(matlab program graphics and image processing, pdf format.)

这是一个数字信号处理的matlab源程序，程序里包含快速傅里叶算法等(This is a digital signal processing matlab source, the program contains the fast Fourier algorithm)

说明：  求解参数估计的常用算法——EM，即期望最大化算法，用于代替样本量不完全时的极大似然估计算法。(Common algorithm for solving parameter estimation- EM, expectation maximization algorithm is used to replace the sample size is not completely at the maximum likelihood estimation algorithm.)

离散余弦变换dct算法详细讲解，并在matlab上进行图像稀疏分解与重建的图像处理仿真。(Discrete cosine transform DCT algorithm is explained in detail, and the simulation of image sparse decomposition and reconstruction of image processing in matlab.)

加入路面激励模型的磁流变减震器伪静力学模型的simulink程序(the simulink proceducer of MR damper s non-force mode of inputting road mode )

三电平逆变，其畸变系统THD比两电平稍好(PWM Generator (3-Level) Block Example)

OFDM信号的编码译码仿真，英文说明更详细。(This simulation script set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded back. Imagerx.m decodes the WAV to extract the data. settings.m contains all the common settings to specify all the simulation parameters such as FFT size, number of carriers, input data source file, input and output WAV files, etc. See settings.m for more details. Note: The both the receiver and transmitter must have a copy of the input data file, as this is used for calculating the exact number of data words in the transmission. The scripts should work as extracted. Just run imagetx.m to generate the OFDM signal. Then run imagerx.m to decode the signal. The initial settings transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be compared with the original data by listening to the two wave files.)

code for computing the entropy of gray scale image, including to calculate the local entropy (especially for matlab 7.0 and lower that dont have entropy and entropyfilt function)
