本文在分析移动无线信道衰落特性的基础上,阐述了OFDM系统的基本原理,主要研究了OFDM通信系统中的基于导频符号的信道估计问题,分析了几种经典的信道估计算法以及相关的关键技术环节。 在此基础上介绍了OFDM技术在现实中的一个应用——WLAN IEEE802.11a系统模型,利用Matlab仿真软件完成OFDM系统信号生成、噪声生成、导频插入、循环前缀、调制、解调等部分的设计,最后结合计算机仿真对系统关键技术(导频、循环前缀、估计算法)的有效性和可行性进行了全面的分析与比较。适合matlab研究(Based on the analysis of mobile channel fading characteristics based on the OFDM system on the basic principles of research in the OFDM communication system of the pilot symbols based on channel estimation problem, an analysis of several classical channel estimation algorithm and the associated key technical links. On this basis, introduced OFDM technology in a practical application- WLAN IEEE802.11a system model, using Matlab simulation software to complete OFDM signal generation, noise generation, pilot insertion, cyclic prefix, modulation, demodulation and other parts of the design, the final combination of computer simulation of the system of key technologies (pilots, cyclic prefix, it is estimated that algorithm) the effectiveness and feasibility of a comprehensive analysis and comparison. Suitable for research matlab)

T7te Foundations of the Science of War is a compilation of material presented by Fuller when he was chief instructor, Staff College, Camberley. Dating 1926, it is the culmination of his theoretical writings and an early attempt to fit mechanization into the fabric of European warfare. In this work, Fuller presents a comprehensive theory of war. While it does not reach the heights to which Fuller aspired, it retains the ability to stimulate and provoke thought seventy years after it first appeared.

说明：  用四阶古典RK方法解初值问题： 取h=1/8。每隔8步打印出数值解与真解的值（u(t)=(t^2)/2-t），画出它们的大致图像，并对产生的结果做出解释。 (with four bands classical RK method for initial value problems : from h = 1/8. Every eight-step numerical solution print and in the true value (u (t) = (t ^ 2)/2-t), they generally draw the images, as well as the results of an explanation.)
