OFDM Moddel in matlab

说明：  FIR汉明窗滤波器和IIR双线性变换法设计的低通滤波器，用于心电信号的滤波。(Hamming window FIR and IIR filter design bilinear transform low-pass filter for filtering ECG.)

以MATLAB將影像做邊緣偵測以及邊緣強化， 邊緣偵測分別為Prewitt以及Canny， 邊緣強化是將邊緣做銳利化(MATLAB will do to the image edge detection and edge enhancement, edge detection, respectively Prewitt and Canny, edge enhancement is done to sharpen the edge)

emlog经典模板分享,自己用的，今天分享出来大家研究。(Emlog classic template share, for my own use, we study today to share out.)

说明：  基于HMM的说话人识别系统，包括提取MFCC特征，特征对比等。(A speaker recognition system based on HMM,included the extraction of MFCC features and features comparison)

说明：  包括三个.M文件,分别用于处理生成直方图,图象的线形拉伸和均衡化(Of three. M document for the deal to generate the histogram, respectively, the linear image stretching and equalization)

说明：  在MATLAB下的数字信号处理的一些应用和实例(Under the MATLAB digital signal processing applications and examples of some)

用蒙塔卡罗搜索方法从所测量值中获取误差最小值，并求出误差(With the Mundaka Luo search method from the measured value of minimum error is obtained, and the calculated error)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
