这是有关MATLAB学习的一些编程技巧和使用的一个程序示例(MATLAB STUDY)

Information to do OFDM using MATLAB application.

Numerical Computing with MATLAB （by Cleve Moler) is a textbook for an introductory course in numerical methods, Matlab, and technical computing. The emphasis is on in- formed use of mathematical software. We want you learn enough about the mathe- matical functions in Matlab that you will be able to use them correctly, appreciate their limitations, and modify them when necessary to suit your own needs. The topics include * introduction to Matlab, * linear equations, * interpolation, * zero and roots, * least squares, * quadrature, * ordinary di?erential equations, * random numbers, * Fourier analysis, * eigenvalues and singular values, * partial di?erential equations.(Numerical Computing with MATLAB (by Cleve Moler) is a textbook for an introductory coursein numerical methods, Matlab, and technical computing.

黄金分割法，用于一维线性优化，输入相应目标函数，可得最优变量(Golden method for one-dimensional linear optimization, enter the appropriate objective function, we can get the optimal variable)

a programm to generate triangular for finite element method

说明：  平行射线滤波反投影，算法简单，通过对投影滤波后，重建的图像效果好。(Parallel rays filtered back projection algorithm is simple, by filtering the projection, the reconstruction of the image effects.)

说明：  线性卡尔曼滤波模型，利用simulink模型搭建(linear Kalman filter and Simulink are used to build the model in detail)

this file consists of the turbo code in the AWGN channel. the simulation will nearly take 20 min to simulate but it will produce an excellent output with reaching the Shannon s limit exactly at 0.5db.

基于互功率谱的时延估计，ofdm系统仿真 含16qam调制 fft 加窗 加cp等模块，有较好的参考价值。( Based on the time delay estimation of power spectrum, ofdm system simulation including 16qam modulation fft windowing modules plus cp, There are good reference value.)
