OFDM系统中基于DFT的信道估计技术仿真(OFDM system channel estimation based on DFT)

Image processing codes

基带传输： 欲传送的01比特流 + 码型变换（HDB3码） + 基带成型网络（采用升余弦滚降系统）+ 信道 + 码型反变换 + 01比特流。 (Baseband transmission: To send the 01 bit stream+ code type transformation (HDB3 code)+ base-band forming network (with raised cosine roll-off system)++ code based channel inverse transform+ 01 bit stream.)

various coding..........................

用DCT方法嵌入一个水印图片，并生成R层图片(DCT method to use a watermark embedded images, and generate R layer picture)

说明：  给出了五对角方程组的Matlab求解编程，并且附有误差函数，实用性强(solve for Pentadiagonal equations using matlab language.)

说明：  利用蚁群算法求解tsp（旅行商）问题，给出遍历方案，最后求出最短路径。(Ant colony algorithm for tsp (TSP) problem, given traversal solutions, and finally find the shortest path.)

关于滤波的程序，可以减少Gipps效应，提高信号的分辨率。(On filtering procedures, can reduce the Gipps effect, improve the resolution of the signal.)

Some features and classification function

ofdm 非常详细的程序，有很多子程序，很经典，有用哦！(ofdm simulation)
