查询词典 twiddle

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。

Why bother trying to compete for world firsts if the leading guild has to twiddle their thumbs waiting for the next stage to be open, watching everyone and his mother catch up.

I think the Sunwell gate "idea" was the final blow. Why bother trying to compete for world firsts if the leading guild has to twiddle their thumbs waiting for the next stage to be open, watching everyone and his mother catch up. Why bother race to the finish line when it''s only Kil''jaeden that matters?

我认为太阳井开门的事件是一个败笔，一个世界的FD让我们觉得无比烦心世界的一流工会全部都茫然地等待着下一道大门的开启，看着其他的公会以致自己老妈的公会有足够的时间达到于自己不相昆季的水准为啥子不直接把这种队伍扔到最终BOSS基尔加丹面前？

After doing that, the paper points out the universal architectures of the high-speed real-time signal processing system and describes how to implement them.. Since FFT plays an important role in digital signal processing, implementing FFT with FPGA is presented and the total realization graph is designed. For improving speed and decreasing computing complexity, high efficiency multiplier algorithm is used to realizing twiddle factor multiplier of butterfly processing unit.

最后本文描述了数字信号处理系统结构的实现方法，指出常见的高速、实时信号处理系统的四种结构；由于FFT算法在数字信号处理中占有重要的地位，所以本文提出了用FPGA实现FFT的一种设计思想，给出了总体实现框图：重点设计实现了FFT算法中的蝶形处理单元，采用了一种高效乘法器算法设计实现了蝶形处理单元中的旋转因子乘法器，从而提高了蝶形处理器的运算速度，降低了运算复杂度。
