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。

Specifies the top y-coordinate, offset from the baseline, of the receiver's longest ascender.

定义的顶部y坐标基於接收者最长顶部基线的偏移。

Under the assumption that the channel state information was available only at the receiver,the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergodic flat fading channel were derived.An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.

以信息论的观点为基础，在假设信道状态信息仅收端已知的情况下，采用等功率发射方案，研究了瑞利衰落信道下MIMO系统各态历经信道容量，推导了三种特殊MIMO信道的各态历经信道容量表达式，以及在小信噪比下等收发天线MIMO系统的容量近似公式，并通过仿真进行了验证，仿真结果表明该近似公式比较精确。

Secondly, The optimal CDMA receiver in AWGN channel is a NP complexity problem in synchronous and asynchronous transmission.

其次，在同步和异步传输中最佳多用户检测都是一个具有NP复杂度的组合优化问题。

The asynchronous transmission mode provides for communication with no timely restrictions. Packets reach the receiver as fast possible.

在异步传输模式中，信息的传送不受时间条件的约束，数据包总是尽可能快地被送达接收端。

Electrical signals produced by unwanted sources (atmospherics or receiver noise or unwanted transmitters).

由不必要的源头产生的电子信号（大气干扰或接收器噪音或有害发射。

We unpacked our attache cases, which contained our tools and a small radio receiver.

我们打开了我们的手提皮箱，里面装着我们的工具和一部小型无线电接收机。

The receiver's high-current capability enables it to effortlessly drive even difficult loudspeaker loads, while ultrawide bandwidth provides far superior phase linearity, lower distortion, greater high-frequency headroom, and more accurate frequency response in the audible frequency range.

接收器的高电流能力，使它能够毫不费力地驱动扬声器甚至难以负荷，同时提供超带宽远远优于阶段线性度，低失真，更多的高频率余量，以及更准确的频率响应的发声频率范围。
