OFDM的信道估计
全文22页 约12000字 论述翔实
摘 要
OFDM技术作为新一代的通讯技术，已被广泛应用于通信系统以及广播式音频和视频领域中。随着该技术的不断完善，其已经日益渗透到了我们的日常生活中。本文的主要研究课题是正交频分复用（OFDM）系统的信道估计，前两章主要对正交频分复用（OFDM）系统的发展现状，以及其相关技术和基本原理进行了简要的概述。其中，对OFDM系统的工作原理，工作模块以及技术特点等都作了比较详细的论述。
从第三章开始，本文主要论述了信道估计的算法。首先，本文介绍了正交频分复用系统信道估计的重要作用，在此基础上，本文详细的介绍了信道估计算法的原理以及基本构造思想，利用数学建模的方法较为直观的反映了信道估计算法的特性，并系统的阐解了算法的工作流程。其中，在论述系统模型建立的过程中，本文利用公式以及仿真图对系统建模作出了比较全面的分析。而在对仿真结果的分析过程中，本文大量引用得到的试验结论进行验证，从而使信道估计算法在试验的层面上得到了准确的论证，使有关信道估计算法的问题都作了比较全面的阐述。

ABSTRACT
As the new generation communication technique. OFDM technology has already used widely in the audio, video and communication system of the radio type at present. It has already permeated through our daily life day by day. This textual main research topic is the channel estimation algorithm of Orthogonal Frequency Division Multiplexing. From two of the chapters, this text has brief summary the handing, dividing, replying and using (OFDM) the systematic current situation of the development frequently mainly, and its also relevant technology and basic principle carry on the brief summary. Among them, to the principle of OFDM system, job module and the characteristic of the technological which have been done the detailed argumentation.
Begin from the chapter three, this text expound the fact of the algorithms that the channel estimation mainly, first of all, this text has been introduced and the important function of the channel estimation algorithm of Orthogonal Frequency Division Multiplexing ,on this basis, this text Introduce the detailed introduction of the channel estimation algorithm, also essentialing structure. Utilizing the characteristics of the channel estimation algorithms of reflection with comparatively ocular method of mathematics modeling.this text also has explained the solved of the work about the channel estimation algorithm. Among them, during the process of describing the systematic model to set up, this text utilizes the formula and picture to make more overall analysis about modeling systematically. In the course of analysis on artificial result, a large number of of this text quotes conclusion to got to verify. Thus make the channel estimation algorithms get accurate demonstration on the aspect of the test. Make the relevant problem have a overall elaborate about the channel estimation algorithm.
