不错的OFDM系统仿真程序。包括了整个系统所需的仿真程序。(Good OFDM system simulation program. Including the entire system simulation program required.)

it is project for servillence system system.

EM@matlab是一个有限元工具包，适用于静力和偏微分方程的演变(AFEM@matlab is a MATLAB package of adaptive finite element methods (AFEMs) for stationary and evolution partial differential equations in two spatial dimensions)

This program return the average centrality for a graph for different value of x.

程序主要是求一段音频数据的基音频率 jiyinzhouqi.m --------求基音周期 find_maxn.m --------求自相关函数的最大值 test2.wav --------程序中用到的示例wav数据文件(The program is mainly the fundamental frequency for an audio data Jiyinzhouqi.m- for pitch period Find_maxn.m- the maximum value of autocorrelation function Test2.wav: the procedures used in the example of wav data file)

非常不错的书籍，《微粒群算法》供8章和2个附录，依次上传第一章绪论(Very good books, Particle Swarm Optimization for Chapter 8 and Appendix 2, followed by From Chapter I Introduction)

关于bpsk调制和解调，进行模拟调制，自行编写绝对正确(About bpsk modulation and demodulation, to simulate modulation, self-preparation is absolutely right)

常见的基于人类视觉特性的图像增强算法由于是同时完成动态范围压缩和对比度增强,导致增强图像的整体对比度不高、边缘部分效果不佳.通过分析人类视觉系统的全局和局部自适应调节原理及人眼视网膜神经节细胞感受野的传输特性,提出一种仿生图像增强法.为适应人类视觉系统对光强的主观感觉特性,对图像作全局亮度对数变换 并利用人眼的主观亮度感觉与实际光强的对数呈局部线性关系的特性,采用视网膜神经元感受野三高斯 模型来调整亮度图像的局部对比度 最后利用线性变换恢复图像的彩色信息.实验结果表明,该算法的增强效果良好,特别是对于图像边界处,既能很好地增强边缘对比,又可有效地提升区域亮度对比和亮度梯度信息.
