图像匹配的经典算法和改进，上海交通大学内部数据库提供(Classical image matching algorithm and improved internal databases, Shanghai Jiaotong University)

说明：  本程序为OFDM系统中基于LSE的信道估计(This procedure for the OFDM system channel estimation based on the LSE)

说明：  线性调频信号的产生及频谱分析并画出频谱图(Linear FM signal spectrum analysis)

功率谱估计的各种方法，包括经典法和现代法的matlab实现，不是通过调用函数，而是根据算法的思想实现的，希望对大家有用。(The power spectrum estimation methods, including the classic method and modern method of Matlab implementation, not by calling the function, but according to the idea of ​ ​ the algorithm to achieve, and the hope that useful.)

通信原理课程设计，包括各种调制，信道编码等。有解释，图形，源码。(Communication theory course design, including modulation, channel coding. Have explained, graphics, source code.)

利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)
