BER simulation of BPSK OFDM with a rectangular filter

熟悉数值方法在matlab中的运用，灵活运用各类绘图函数，边学边用，加强对数值方法的认识。(Familiar with numerical methods in matlab in the use of flexible use of various types of drawing functions, learning while using, to enhance understanding of numerical methods.)

基于standford大学cioffi教授的经典算法，计算有线信道的最佳判决反馈滤波器系数。(Calculate the optimal DFE coeffients based on the algorithm propoased by prof. Cioffi)

— In ultra-wideband (UWB) indoor dense multi-path transmission environments, traditional coherent Rake receiver requires estimation of channel parameters. Moreover, in order to collect enough signal energy from dense multi-path components, the number of Rake fingers must be large enough. Consequently, the receiver structure is too complex to be implemented in practice.

这是一个虹膜识别检测的matlab程序，程序很完整(This is an iris recognition matlab testing procedures, the procedures are complete)

解相关及最小均方误差和传统多用户检测器的比较(Decorrelating and MMSE and traditional multi-user detector comparison)

High accuracy optical flow using a theory for warping(The files optical_flow_brox.m and optical_flow_sand.m are the files you need to run. optical_flow_brox.m implements the traditional algorithm. Just replace the first lines where images are read, with your image, and start the process. optical_flow_sand.m implements a variant presented in CVPR 2006. Again just replace the lines "img1 = imread( ... )" and "img2 = imread( ... )" with your images and the rest is automatic. The variable num_levels controls the number of images in the laplacian pyramid to be constructed. Change it to suit your convenience.)

sift特征点匹配程序，实现特征点匹配，.m文件，直接在matlab中运行即可。(sift feature point matching process, to achieve feature point matching,. m files can be run directly in matlab.)

说明：  一个三维共形时域有限差分方法，很实用，对于处理三维FDTD算法问题，很有实际价值。(A three-dimensional conformal finite-difference time domain method is very practical.It has practical value to deal with the problem of 3D fdtd algorithm.)

说明：  可以用这份代码做粒子滤波，效果还行，这个是无迹的算法(This code can be used for particle filtering.)
