龙格库塔法解简单运动方程,单自由度方程适用，一个简单的应用例子(Solving simple equations of motion Runge-Kutta)

Cognitive radio allows unlicensed users to access licensed frequency bands through dynamic spectrum access so as to reduce spectrum scarcity. This requires intelligent spectrum sensing techniques like co-operative sensing which makes use of information number of users.

对振动信号进行时域分析，得到模态参数的方法。(The vibration signal in time domain analysis, modal parameters.)

说明：  数值分析的部分matlab代码分享，如有错误还请见谅！(Part matlab code analysis of numerical analysis, please forgive me if there is any mistake.)

这是一篇很好的有关信道估计的文章， 可以用来快速的了解信道估计的基本内容(and MAI induced by multiple-input, multiple-output channels. In particular, this article reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm, and constant modulus algorithm along with their relations, performance, and improvements. Several advanced applications of these algorithms are illustrated, including blind channel estimation, simultaneous estimation of multiple time delays, signal-tonoise ratio (SNR) boost by blind maximum ratio combining, blind beamforming for source separation in multipath, and multiuser detection for direct sequence/code division multiple access (DS/CDMA) systems in multipath.)

MATLAB的一些基本function代码(Some basic function of MATLAB code)

这是自己整理很久的一片有关于运动目标检测与跟踪算法研究的论文，用matlab实现的。(This is a long-own finishing about moving target detection and tracking algorithm paper, using matlab to achieve.)

matlab实现人脸识别系统！给定一张人脸图像，能在一堆图片中识别出来！(matlab to achieve face recognition system! Given a human face images, can be identified in a pile in the picture!)

数字波束形成，阵列信号，里面包含了经典DBF算法和基于FFT多波束形成算法，适合初学者，自己编的(Digital beamforming, array signal, suitable for beginners, own)
