Blend various advantages of the coding project of the parameter audio frequencies in the meantime, carried on adjustment on the coder structure, have to a certain signal more the mold piece of coding result, if wave structure analytical transformation short time of the mold piece, double the composition examine and double the transformation short time mold piece etc.

论文针对目前一部分参数音频编码音源模型在高采样率下出现的各种问题进行改进，提出一种而向44.1KHz/48KHz高采样率音频信号的参数音频编码系统，使用了可以有效兼顾码率与音质的多分辨率正弦模型和多分辨率ERB噪声模型。

Blend various advantages of the coding project of the parameter audio frequencies in the meantime, carried on adjustment on the coder structure, have to a certain signal more the mold piece of coding result, if wave structure analytical transformation short time of the mold piece, double the composition examine and double the transformation short time mold piece etc. is an options to bring into coder, from user while coding according to small together source voice document of small together characteristics, decide whether use and how use, but these vivid constitutions can through a code flow in define several good to mark ratio in advance tell a decoding machine especially, constituting decoding machine is little with complications to without direct influence.

同时融合多种参数音频编码方案的优点，在编码器结构上进行了调整，将只对某类信号有较好编码效果的模块，如谐波结构分析模块、双变换短时成分检测与双变换短时模块等，作为选项纳入到编码器中，由使用者在编码时根据小同源声文件的小同特点，来决定是否使用和如何使用，而这些灵活的设置都可以通过码流中预先定义好的几个标示比特位来告知解码器，对解码器本身的构成与复杂度少没有直接的影响。

The material can be presented as text, graphics, animated graphics, audio, video, or a combination of these.

Wire break, audio deviation and unit aphonia are the common breakdown which not only occurs in the low-end headphones, but also happens in some high-end ones frequently.

断线、偏音、单元失声是比较常见的现象，并且这一现象并不拘泥于低端耳机，一些高端耳机也经常会显现故障。

Two and a half years ago, when certain audiophiles were praising the original iPod shuffle as the best-sounding iPod in the family, Apple surprised some users by agreeing: audio quality was, a company representative explained, a "moving target," and with that shuffle as a gold standard, the goal would be to bring other members of the family up to that level.

两年半前，当一些音频达人开始称赞一代shuffle为ipod家族音质之王时，Apple让一些用户在惊讶中赞同：所谓音质就是一个"移动靶"，而当时的shuffle无疑就是那个金牌选手，这个成功理所当然的会使ipod家族中的其他成员找到努力的方向而达到更好的音质。

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。
