关于多径效应的MATLAB仿真程序，共四个。这个matlab代码从两种情况下生成传输信号频域的方面比较。(Multi-path effects on the MATLAB simulation program, a total of four. The matlab code is generated from the two cases signal transmission aspect of frequency domain comparison.)

ldpc在BSN信道下的性能仿真，程序较简单，但可以运行，仅供参考(ldpc in the performance of BSN channel simulation, the program is relatively simple, but it can run for reference only)

支持向量机的代码库，使用简单，主要用途是基于支持向量机的分类和回归。还包括C-SVM，nu-SVM，一类SVM，epsilon回归等功能。它还提供了用于C-SVM的自动模型选择工具。(Libsvm is a simple, easy-to-use, and efficient software for SVM classification and regression. It solves C-SVM classification, nu-SVM classification, one-class-SVM, epsilon-SVM regression, and nu-SVM regression. It also provides an automatic model selection tool for C-SVM classification. This document explains the use of libsvm. )

该代码是对人脸进行光照处理，先进行gamma变换，然后进行Dog双边滤波，然后进行灰度亮度的均衡。该方法能够有效提高光照变化的情况下的系统识别性能(The code is the human face of light treatment, the first for gamma conversion, and then Dog bilateral filtering, then the brightness of the gray balance. The method can effectively improve the illumination changes in the case of system identification performance)

可以用matlab来验证经典的zipf分布定律。(Can be used to verify the classic zipf matlab distribution law.)

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(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get a certain amount of diversity gain)

gps的信号发生方式，直接生成它的信号，还是有一定的参考价值的(gps signal generating means, direct generation of its signal, or have a certain reference value)

对超宽带定位的基本原理进行了探讨，重点讨论了经典算法中的非迭代算法和迭代算法，对其优缺点进行了对比分析，并以实例说明了超宽带定位技术的优良性能。(UWB positioning on the basic principle is discussed, focusing on the classical algorithm of non-iterative algorithm and the iterative algorithm, its advantages and disadvantages are compared, and to locate examples of the ultra-wideband technology for excellent performance.)

说明：  模拟退火工具箱，里面含有很全的matlab语言模拟退火算法(Simulated Annealing toolbox, which contains a very wide language of the simulated annealing algorithm matlab)
