Lagrange乘子法 用于解约束最优化问题 (Lagrange multiplier method for the solution of unconstrained optimization problem)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(AF and DF simulation procedure code)

This program describes that how the binary data is transmitted by dividing data into frames. it also analyse the Bit Error rate by 16 QAM method and viterbi decoding method.

这是一个用MATLAB编程的64QAM程序，希望大家多提意见。(This is a 64QAM using MATLAB programming procedures, hope that we do so.)

利用matlab内置的算子,做出的各种边缘提取的比较(Using matlab built-in operator, made by comparison of the various edge detection)

用于检测两个信号的延时情况,应用方面非常广泛(for detecting signal delay, the application is very extensive)

很好用的Dijkstra求最短路的MATLAB程序，带注释，都能看懂。。。。(Find a good use of the Dijkstra shortest MATLAB programs, with comments, can understand. . . .)
