长周期光纤光栅有着很广泛的应用前景,关于长周期光纤光栅的理论分析也很成熟,而具体如何实现其传输谱特性的 仿真却报道很少(Long-period fiber grating has a very broad application prospects, on the theory of long-period fiber grating analysis is also very mature, and specifically how to achieve its transmission spectral characteristics of the simulation are few reports)

说明：  kmeans 算法的实现，编译已经通过，希望对大家有帮助(kmeans algorithm, the compiler has been passed and we hope to help)

建立一个WS小世界的模型，返回该模型的连接矩阵(establish a WS small world model and obtain its adjency matrix)

产生一个含噪声矩形波，用小波分析和傅里叶变换分析进行信号噪声消除并比较两者的去噪声能力。(Produce a rectangular wave Noisy, wavelet analysis and Fourier transform analysis of signal-to-noise cancellation and compare the ability of both to noise.)

S-curve simulation in matlab

单位圆的内插实现，里面有4种内插算法：拉格朗日插值、牛顿插值、分段线性插值、分段样条插值、以及插值误差范数估计等等(Interpolation to achieve the unit circle, which has four kinds of interpolation algorithms: Lagrange interpolation, piecewise-linear interpolation, sub-spline interpolation, as well as Norm interpolation error estimates, etc.)

Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects. This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts: 1)Analog imperfection compensation for the direct upconversion transmitter 2)Design a DPD based on a memory polynomial predistorter 3)Performance evaluation via a number of parameters such as:EVM,PSD,SNR,

对文本文件进行huffman编码，并显示huffman树(to the text document for Huffman coding, and that Huffman tree)

Matlab编程学习课件，是初级学习非常重要(Matlab programming learning courseware, is the primary learning is important)

this matlab code is for commande of system by PI controller
