Acoustic-Echo-Cancellation

该文提出的改进的算法是针对图像压缩编码的，针对四叉树，提出的方案产生了客观和特殊结构的二进制编码。(This paper presents an improved algorithm for image coding, quadtree for the proposed programs have the objective and the special structure of the binary encoding.)

基于MATLAB/simulink的永磁同步电机仿真模型.空间失量磁场定向算法222(Based on MATLAB/simulink simulation model of permanent magnet synchronous motor. Spatial loss field oriented algorithms 222)

说明：  输入一个样值电平,对它进行13折线编码,画出编码波形.(Enter a sample value level, its 13-line code, draw the waveform coding.)

利用matlab工具，实现了计算数值计算中的不动点法的程序解法(put the one way of fixed dot method of compute canculating into practice with the tool of MATLAB)

基于matlab的彩色图像转成灰度图像，然后进行图像旋转并画布扩大，最后进行均值插值(Matlab-based color image into gray image, and then expand the image rotation and canvas, and finally to mean interpolation)

说明：  Vblast，不同的编码方式qam，qpsk等，MMSE检测。不同天线数目设计。(very good for vblast MIMO beginners)

MATLAB simulation of OFDM transmitter and reciever

文件里包含了扩频系统中的m序列码的产生，产生以后的相关运算(File contains the m-sequence spread spectrum system code generation, is produced in the relevant operations)

main executing reference usage: observeWaveletDecompositionBenchmark_N_levels.m The objective is to illustrate wavelet decomposition, and to describe how operations may be done in the wavelet domain before the reconstruction. The demo decouples the wavelet operations (transform, operation in wavelet domain, and reconstruction) from the plotting. A PSNR and MSE describes the possible distortion (however minimal) of the forward and inverse wavelet transform. * Caveat: The image display may be subjected to the selected target image. The objective is to provide a simple framework for the understanding of working with wavelets.
