THE DESIGN AND IMPLEMENTATION OF DECIMATOR BASED ON FPGA ABSTRACT Software radio is regarded as the developing direction of communication in future, and as one part of this, decimator change the high rate dataflow to a lower one, which meets the require of real-time processing and makes software radio come true.

软件无线电是未来通信的发展方向，而作为其重要组成部分之一的抽取器，将难以实时处理的高速数据流变为低速率信号，使软件无线电的实现成为可能。

In this paper, a new structure of Low Voltage Differential Signal transmitter circuit is presented.

摘 要：本论文给出一种用0.18μm的CMOS工艺设计，工作电源电压是1.5V，可实现为2.5Gbps数据流的发送的LVDS(Low Voltage Differential Signal)发送器。

Them. What would happen if you ran into a clever disassembler that actually analyzes

个聪明的反汇编器，它一条一条的分析每一条指令，追踪每个数据流的流向会怎么样

Many objects can be distributively processed so that the potential parallelisms with different granularities may be exploited easily.

该模型将多媒体数据流在I／O级、处理级和传输网络级进行对象分解，多个对象分布处理，可充分开发不同粒度的并行性。

For example, streams that emanate from the sensors will have to be mined to extract useful information.

例如，传感器发出的数据流将不得不提炼出有用的信息。

The important goal of video transmission is that the users can receive the video stream equably and continuously over the network.

网络视频技术的一个重要目标是确保用户通过网络得到均匀而连续的视频数据流。

The Secure File Transfer Protocol provides secure file transfer functionality over any reliable data stream, SSH in this case.

安全文件传输协议提供安全的文件传输功能的任何可靠的数据流， SSH的在这种情况下。

Up to this time, the major challenge to sign language recognition is how to develop approaches that scale well with increasing vocabulary size In this paper, an approach to large vocabulary, continuous Chinese sign language recognition is presented, which uses subwords instead of whole signs as the basic units Since the number of subwords is limited, HMM based training and recognition of the CSL signal become more tractable and have the potential to recognize enlarged vocabularies Furthermore, the proposed method facilitates the CSL recognition when finger alphabet is blended with gestures About 2400 subwords are defined for CSL One HMM is built for each subword, and then the signs are encoded based on these subwords A decoder that uses tree structured network is presented Clustering of the Gaussians on the state, language model and N best is used to improve the performance of the system Experiments on a 5119 sign vocabulary are carried out, and the correct rate is over 90% for continuous sign recognition

迄今为止，手语识别面临的最大问题是如何解决词汇集易扩充的连续识别提出一种大词汇量连续中国手语识别方法，将词根作为识别基元，由于基元的数目是有限的，因此基于HMM的手语信号的训练和识别变得比较容易处理，可以实现更大词汇量的识别除此之外，所提方法还有利于实现手势语和手指语的混合识别从中国手语中共整理出2 4 0 0多个词根，为每个词根建一个并行的HMM模型，对各数据流的HMM模型进行聚类，确定出手语识别的基元根据这些基元对手势词编码，并建立了树状搜索网格，使用状态结点上高斯密度函数聚类、语言模型和N Best方法提高系统的速度和精度对 5 119个手语词做了实验，连续语句的识别率可在 90 %以上

The main function and structure of this system are designed and described by data flow chart.

设计了系统的总体功能结构，并对其进行了数据流图描述。

In this paper, a computer-aided Generation Edit of Data Flow Diagram is presented and implemented.

本文提出并初步实现计算机辅助的数据流图生成编辑。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
