频率响应分析 系统Nyquist曲线的绘制；系统Bode图的绘制(Frequency response analysis ；Nyquist curve drawing system；系统Bode图的绘制)

简单的OFDM仿真，采用QPSK调制，有串并转换，保护间隔，fft/ifft等(Simple OFDM simulation using QPSK modulation, there are serial to parallel conversion, guard interval, fft/ifft etc.)

说明：  　 随着微加工技术的发展和日益成熟 ,微型化光谱仪的研究得以快速发展。和传统的 微型光谱仪相比 ,基于调制原理的光谱仪具有高光通量、 高分辨率的性能优势 ,可广泛应用于生物、化学、 医学等许多领域中对微弱辐射信号的探测。介绍了几种类型的调制光谱仪的结构特点和关键技术 ,分析了设计与制作微型调制光谱仪过程中存在的一些关键问题与难点 ,并总结了该领域的研究进展和发展趋势。(　The mat uration of the optical micro2elect ro mechanical systems technology has imp ul sed t he development of t he micro spect rometer . Compared to the t raditional micro spect rometer , t he spect rometer based on modulation can be used in biological , chemical and medical fields to detect t he faint signal s due to it s inherent advantages. An overview of t he development s of t he micro spect rometer based on modulation is presented. The key p roblems in designing and fabricating t he Fourier t ransform spect rometer ( F TS) are discussed , and t he progresses made worldwide in t his field are al so presented.)

使用双线性内插法 在matlab下实现图像的整数倍放大(use bilinear interpolation method in Matlab under several times for the entire image to enlarge)

this is a very good mfile for small signal analyze

voltage-boosting converter, named as KY converter, was proposed, which provides low output voltage ripple and is very suitable for supplying power to devices that must operate under low-ripple conditions.

该算法功能是运动视频帧目标检测，实验效果较好，值得一看(The algorithm feature is motion video frame target detection experiment better, worth a visit)

Zernikz descriptors: the similarity measure based on the descriptor should deliver a similarity ordering that is close to the application driven notion of resemblance.

To reduce the piracy .....here we use a watermark technique...
