Abstract ： to obtain the high frequency ( hf ) array signals , an applied circuit called hf array signals generator is designed using dsp and duc ( digital up converter ) . the generator simulates the generation of output signals of 9 - element arrays with different array format , different direction of arrival ( doa ) and existing cochannel signals respectively 为了在实验室中获得短波天线阵列信号，应用dsp芯片和duc芯片(数字上变频器)设计了一个实用电路短波阵列信号发生器，模拟实现了短波九元天线阵的多种阵型、不同来波方向及存在同频多信号时的阵列输出信号。
The basic characteristics , framework , principles of dominant parts and application of those are studied and illustrated . at the last chapter , by devising a short - wave radio station aforementioned fundamental theories are put into practice especially digital modulation , demodulation , ddc and dug etc . the implement framework and design method of sdr are discussed by data transmission of voice including dug modulation in transmit module and ddc demodulation in receive module . moreover , satisfied results are obtained by validation on the sb3410 platform in bluewave system 针对论文设计中用到的两个比较重要的器件hsp50214b下变频器和hsp50215上变频器，作了较为深入的研究并给出了详细的描述，包括基本特征、框架结构、各主要部分原理及在设计中的应用；在最后一章，通过设计一个短波无线电台，将前面的基础理论尤其是数字调制、解调及数字上、下变频等应用于实践中，通过实例讨论话音数据传输的软件无线电实现结构及设计方法，包括发射模块中的上变频调制和接收模块中下变频解调等，并在bluewave系统的sb3410平台上运行验证，取得了较为满意的结果。
We know that ronald has already gathered quite some reputations through his previous films , and we were trying to bring his sense of humor into our work , hoping that it could mutually benefit both of us . while we have preserved ronald s unique approach in comedy acting , we would also make the structure of the drama more intact and coherent 我想在几部郑中基的喜剧推出之后,在观众之间亦产生回响,甚至在票房数字上也有一定的回响反应,而我们就想把郑中基的喜剧感,放入我们这个班底之中,使我们的戏剧感放大。
The digital upward frequency conversion is the key element of the waveform synthesis . at the same time , basic theoretical analysis and optimum design are done for pci bus slave interface , fifo , transmit signal processor , digital - to - analog converter and logic control 本文对波形合成技术的核心? ?数字上变频进行了深入细致的研究和介绍，同时对波形合成器中的pci总线接口、先进先出缓冲器、发射信号处理、数模转换及逻辑控制等部分进行了分析和优化设计，给出了最佳设计方案。
Meanwhile , given the way in which the gdp figures are compiled based on what is called the expenditure approach the increasing current account surplus will , statistically , be reflected readily in the gdp figures , which will need to be interpreted against this complex background 不过暂时来说，受到本地生产总值的编制方法即所谓的支出计算方法影响，从统计角度来看，不断增加的往来帐盈馀自然会反映在本地生产总值的数字上。要诠释这些数字，就必须顾及这些复杂的背景因素。
" i would say that we have been beaten physically in our last couple of away games and i do n ' t deny that we need to improve that , " wenger wrote in his programme notes , referring to the visits to bolton and newcastle , where failure ended their already fading interest in this season ' s championship race 从赛后得到技术统计数字上看，在本场比赛中，切尔西队无论是在射中和射偏球门次数方面都要优于阿森纳队。而在犯规次数越位以及受到黄牌警告方面，他们也“领先”于对手。
