QPSK仿真，实现，matlab，m文件(QPSK simulation)

The code assembles various member stiffness matrices of a Q-4 element

本程序用于求解层次分析法中的特征值问题。正互反阵最大特征值和特征向量实用算法，本程序为求和法。(This procedure is used to solve the ahp eigenvalue problems. Is reciprocal array maximum eigenvalue and eigenvector practical algorithm, the procedures for the methods of summation by. )

split step fourier method

基于MATLAB的高等数学问题求解 的程序. 包括 图形处理，数值计算等等(Programs for solving advanced mathematical problems based on MATLAB, including graphics processing, numerical calculation and so on)

The Program helps to remove numbers at the beginning of a Matlab script. It is very useful when one has copied a code from a text into Matlab environment and eager to tun it immediately.

本书简绍了matlab编写有限元程序的整个流程(The goal of this document is to give a very brief overview and direction in the writing of nite element code using Matlab. It is assumed that the reader has a basic familiarity with the theory of the nite element method, and our attention will be mostly on the implementation. An example nite element code for analyzing static linear elastic problems written in Matlab is presented to illustrate how to program the nite element method.)

说明：  简要介绍了OFDM的发展状况及基本原理, 文章对OFDM 系统调制与解调技术进行了解析，得到了OFDM 符号的一般表达式，给出了OFDM 系统参数设计公式和加窗技术的原理及基于IFFT/FFT 实现的OFDM 系统模型，阐述了运用IDFT 和DFT 实现OFDM 系统的根源所在,重点研究了理想同步情况下,保护时隙(CP)、加循环前缀前后和不同的信道内插方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系统模型的基础上,用MATLAB语言实现了传输系统中的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,研究保护时隙、循环前缀、信道采用LS估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。(Generation of OFDM Communication System)
