用MATLAB编写的程序，对经典模型的建立、技术。

用离散数学或图论的术语来说，假设有一个图g=(v,e)，其中v是顶点集，e是边集，设d=(dij)是由顶点i和顶点j之间的距离所组成的距离矩阵，旅行商问题就是求出一条通过所有顶点且每个顶点只通过一次的具有最短距离的回路。 (Discrete Mathematics or use the terminology of graph theory, assume that a graph g = (v, e), where v is the vertex set, e is the edge set, let d = (dij) is a vertex between i and vertex j formed from the distance matrix, a traveling salesman problem is obtained through all the vertices and each vertex only once has the shortest distance through the loop.)

说明：  设计中心波长在1550nm,光栅长度、折射率调制深度等可调，可以仿真出FBG的透射谱(The design center wavelength is 1550 nm. The grating length and refractive index modulation depth can be adjusted.The transmission spectrum of FBG can be simulated.)

LTE链路级的仿真，非常的全面。考虑了现有LTE的大部分技术。MATLAB仿真，有些功能是用C代码写的。http://www.pudn.com/downloads240/sourcecode/comm/wireless/detail1121790.html 的内容的最新版本。(The LTE Link Level simulator simulator is provided with a test simulation scenario that can be used to verify that the simulator runs in the expected way. In the main directory you can execute the LTE_sim_batch_quick_test MATLAB script. This script provides a means to test the performance of an LTE transmission on an uncorrelated PedB channel and flat Rayleigh channel for several transmission modes. Since currently the feedback calculation for the Closed Loop Spatial Multiplexing (CLSM) mode is not implemented, only the Single-Input Single-Output (SISO), Transmission Diversity (TxD) and Open Loop Spatial Multiplexing (OLSM) modes are simulated.)
