matlab从入门到精通第4章书后源码对初学者很有帮助(matlab)

波形产生器,产生方波，正弦波，双曲正割，三角波。高斯，超高斯，亚高斯等等(wave productor)

说明：  四类语音信号的BP神经网络识别： 四个特征信号矩阵合成一个矩阵， 根据BP网络输出找出语音数据属于哪类， 并求出判断正确率(BP neural network to identify four categories of speech signals MATLAB)

数字信号处理matlab工具书。里面涵盖了基本的数字信号处理仿真方法，是初学者的必备宝典。(Digital signal processing matlab tool. Which covers the basic digital signal processing simulation method is essential for beginners Collection.)

A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images.

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)
