Just like that we enjoy the Chinese characters and Arabic numbers, we not only enjoy the beautiful drawing of hieroglyph, beautiful line of " knotting cords to record events ", but also enjoy the representation and abundant meaning demonstrated by characters and numbers … furthermore the rhythm beauty demonstrated by quality logic and quantity logic!

正如我们欣赏中文的文字和阿拉伯数字那样，不仅可以欣赏到"象形文字"的图画美，"结绳记事"的线条美，还可以欣赏到文字和数字所表现的事物的具象以及它们丰富的内涵……还有定性的逻辑和定量的逻辑所呈现的旋律美！

Who discovered Arabic numerals?- Hindu did, instead of Arabic! Formerly,"Arabic numbers" went around to Arab Dom, came down to Europe.Incorrectly relied an erroneous information, on shoes on boots, westill call it as Arabic numeralsnow.

阿拉伯数字实际上是古印度人发明的，后来流传到阿拉伯，又转到欧洲，欧洲人就认为是阿拉伯人发明了这些数字。

Firstly it describes the development ,basic principle and application and propagation characteristic of mobile channel , then investigates the system structure of DAB transmitter and receiver separately and the key technology of realization of the digital audio broadcast system.And then discusses the system component of FFT －the demodulation module of OFDM .The 409- points FFT module employs a radix-4 decimation-in-frequency algorithm, includes arithmetic element , read and write address element ,twiddle factor element and control element , is realized by FPGA. In the end , the result is verified in the matlab .

首先概述了OFDM的发展、基本原理和应用以及移动信道的传播特性，接着分别研究了数字音频广播接收机和发射机的系统结构，以及数字音频广播系统实现的关键技术，然后详细论述了OFDM解调模块FFT的系统结构，主要研究了4096点FFT采用基－4按频率抽取实现的算法，整个FFT模块包括了运算单元、读写地址单元、旋转因子单元以及控制单元，并且在FPGA中进行了硬件实现，并在matlab环境下对结果进行了验证。
