OFDM

数字图象处理系统，使用MATLAB的GUI模块，可实现图象的直方图均衡、灰度化、二值化、缩放、边缘检测、增加噪声、图像变换、去噪等功能。使用时请将fig文件和m文件和图像放在一个文件夹内(photo process system,use matlab)

kalman滤波编程，对误差进行分析，俩个图像(kalman filtering sigma point)

OFDM信道估计代码，通过LMMSE估计、LS估计、SVD估计进行研究。并通过MATLAB仿真平台进行仿真，对三种信道估计算法及它们的性能进行了仿真分析和比较。(OFDM channel estimation)

该程序可用于近红外光谱二阶求导预处理，经本人实测，程序可用。(The program can be used near-infrared spectroscopy second derivative pretreatment, as I found, the program is available.)

PCA用于组成分分析，在labview下编程的，对于初学PCA有一定的帮助(PCA analysis labview)

FEM1D_SPECTRAL_NUMERIC is a MATLAB program which applies the spectral finite element method to solve the problem u = - pi^2 sin(x) over [-1,+1] with zero boundary conditions, using as basis elements the functions x^n*(x-1)*(x+1), and carrying out the integration numerically using MATLAB s quad() function. This function solves the problem u = - pi^2 * sin( pi * x ) for x in (-1,1), with boundary conditions u(-1) = u(1) = 0.

对信号进行频谱分析及滤波，ML法能够很好的估计信号的信噪比,这是一个好用的频偏估计算法的matlab仿真程序。( The signal spectral analysis and filtering, ML estimation method can be a good signal to noise ratio, This is a useful frequency estimation algorithm matlab simulation program.)

实验名称:投资组合分析 实验性质：综合性和研究探索性 实验目的：熟练运用投资组合工具箱，学会构造有效前沿组合的方法，掌握最优投资组合的计算方法；给出投资组合VaR 的值。 实验任务：选择股票并从万得下载数据，计算证券的预期收益率、标准差和协方差，设定一组约束条件，构造最优投资组合并计算该组合的Var值。 实验设备：计算机 实验软件：Matlab2013 Wind数据库 选择一组股票作为投资标的，构造投资组合，通过估计收益率均值、计算方差、协方差，计算该投资组合权重、在险价值、画出有效前沿。(Experimental Name: Portfolio Analysis Experimental nature: comprehensiveness and research exploration The purpose of the experiment is to skillfully use the portfolio toolbox, learn to construct effective frontier portfolio method, grasp the best investment portfolio calculation method, and give the value of portfolio VaR. Experimental tasks: select stock and download data from Wan De, calculate the expected return, standard deviation and covariance of securities, set up a set of constraints, construct the optimal portfolio and calculate the Var value of the portfolio. Experimental equipment: computer Experimental software: Matlab2013 Wind database A group of stocks is selected as investment target, and a portfolio is constructed. By estimating the mean value, variance and covariance of the yield, we calculate the portfolio weight, value at risk and draw effective frontier.)
