本程序实现了matlab自带函数imfillter的功能，是.m文件的形式，参数和imfilter一样可选。程序附有图片，并且在程序最后使用imfilter，便于直接对比观察处理效果。注：本程序是读入RGB图像，转换成灰度图进行处理。(This program implements the function of matlab own function imfillter is. M file in the form of the same parameters and imfilter optional. Procedures with pictures, and last used in the program imfilter, for direct observation of treatment effect contrast. Note: This program is read into the RGB image into grayscale processing.)

matlab图像配准例程，包含了.m文件和图片，值得下载研究(matlab image registration routines, including the. m files and pictures, it is worth downloading study)

OFDM系统，有（2，1，7）卷积码编码，分组交织，viterbi译码(OFDM system, there are (2,1,7) convolutional code encoding, packet intertwined, viterbi decoding)
