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)

Different Modulation schemes are here! like ask, fsk, psk etc!

有限元分析计算的matlab程序，希望对大家有所帮助(finite element analysis of Matlab procedures, we hope to help)

matlab程序 五点滑动平均方法 很好很强大(matlab program five-point moving average method)

本程序是关于预测函数的几个程序，包括阶跃输入以及在干扰情况下的系统影响，控制效果良好，自己可以其中的参数！(This procedure is about the predictive function of several procedures, including the step input, as well as the interference situation in the system under the impact of control works well, the parameters in which they can!)
