计算光子二维晶体米卡良透镜折射率分布的程序，同时给出米卡良透镜在径向的晶体柱半径分布(Calculated two-dimensional photonic crystal lens refractive index distribution of Mika good program, and gives good Mika crystalline lens in the radial distribution of column radius)

matlab制作的数字水印算法原程序，实现整个程序运行还行，共享给大家-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share (matlab digital watermarking algorithm produced the original procedure, also realize the whole process to run line-sharing to the U.S.-jpeg of the Matlab Simulation, and the whole process has run OK, for everyone to share)

DSP程序里IIR滤波结果跟MATLAB仿真结果相差很大是为什么?各位老兄: 我最近利用TI库函数里IIR滤波程序对一组数据进行滤波,IIR系数利用TI公司所提供的eziir.m(matlab程序)程序获得,在matlab里利用相同的系数对相同的数据进行滤波(DSP program results IIR filter with MATLAB simulation results are very different and why? You man: I have the use of library functions in TI procedures IIR filter to a group of data filtering, IIR coefficients provided by the use of TI' s eziir.m (matlab program ) procedures in matlab using the same coefficient in the same data filtering)

说明：  该文档介绍了高速移动情况下，由于多普勒频移导致的ICI干扰问题。描述了问题的产生，解决的算法，并附有自消除、最大似然估计、卡曼滤波参数估计的matlab仿真(introuces the ICI problem in high-speed mobile radion channel.Describe the reasons ,algorithms,such as Self-cancellation,ML,Kalman.And the M files are atteched)

qc-ldpc码编程，围长为6，列重为3，无4环(The algorithm divides rows into three equal groups. The rows are then connnected to form a distance graph which is then transformed in to a matrix. Girth of six is maintained by avoiding four-cycles. No two rows are connected more than once (the row-column constraint).)
