电子信息工程专业外文翻译--滤波器

外文原文一、a question for study or discussion1.Research background and purpose1.1 conceptualizeElliptic filter (Elliptic filter), also known as the Call filter (Cauer filter), is in the passband and stopband ripple of a filter. Elliptic filter when compared to other types of filters, in order under the same conditions with minimal fluctuations in the passband and stopband. Same as its wave in passband and stopband, which distinguish it from the Butterworth filter with flat passband and stopband and flat passband and the stopband ripple or resistance with flat, cut than the snow filter passband ripple.A low-pass filter with a frequency response range of the ellipse:Four-order low-pass elliptic filter frequency response。

1.2 scientific researchIn the low-frequency (600Hz=500KHz) commonly used in band-pass filter, large LC filters, poor stability, stability of Crystal filters, but can only be made of narrow-band filter, bad shock and vibration resistance. Active filters are small, but stability and decay characteristics are often poor, and debugging easy. Ceramic filter is poor and low-frequency seismic performance of low temperature coefficient. And than snow filter Butterworth filter transfer function is a polynomial divided by a constant, for the whole network, all zeros in infinite, only infinite stopband attenuation is infinite, and the elliptic filter in both with zeros and poles on the limited frequency. Zero ripple in the passband, that it has a minimum across the passband and stopband ripple, This is distinguished from Butterworth filter with flat passband and stopband。

Cooperative Peer-to-Peer Streaming:An Evolutionary Game-TheoreticApproachYanChen,StudentMember,IEEE,BeibeiWang,StedengMember,IEEE,W.SabrinaLin,Member,IEEE,Yongle Wu,Student Member,IEEE,and K,.J.Ray Liu,Fellow,IEEE Abstrac t—While peer-to-peer(P2P)video streaming systems have achievedpromising results,they introduce a large number of unnecessary traverse links,which consequengly leads to substantial network inefficiency.To address this problem and achieve better streaming performance,we propose to enable cooperation among “group peers,”which are geographically neighboring peers with large intra-group upload and download bandwidths.C onsidering the peers’selfish nature,we formulate the cooperative streaming problem as an evolutionary game and derive,for every peer,the evolutionarily stable strategy(ESS),which is the stable Nash equilibrium and no one will deviate from.Moreover,we propose a simple and distributed learning algorithm for the peers to converge to the ESSs. ed from the peer’sown padtWith the propo sed algorithm,each peer decides whether to be an agent who downloads data from the peers outside the group or a free rider who downloads data from the agents by simply tossing a coin,where the probability of being a head for the coin is learned from the peer’s own past payoff history.Simulation results shou to the traditional non-cooperative P2P schemes,the proposed cooperative scheme achieves much better performance in terms of social welfare,probability of real-time streaming,and video quality(source rate). IndexTerms—Coopreative streaming,distributed learning,evolutionary,game theory,peer-to-peer(P2P),replicator dynamics.ⅠIntroductionWith the rapid development of signal processing,communication, and networking technologies,video-over-IP applications become more and more popular and have attracted millions of users over the Internet.One simple solution to video streaming over Internet is the client-server service model,where the video is streamed directly from a server to clients.However with the client-server service model, the upload bandwidth of the server grows proportionally with the number of clients, whice makes the large-scale video streaming impractical.To reduce the workload of the server,peer-to-peer(P2P)service model is proposed, where a peer not only acts as a client to download data from the network,but also acts as a server to upload data for the other peers in the network.The upload bandwidth of the peers reduces the workload placed on the server dramatically,which makes large-scale video streaming possible,Recently,several industrial large-scale P2P video streaming systems have been developed,includingCoolstreaming,PPLive,PPStream,UUSee,and Sopcast. Studies show that these systems can support hundreds of thousands of users simultaneously.While P2P video streaming systems have schieved promising results, they have several drawbacks. First, there are a large number of unecessary traverse links within a provider’s network.As observed in ,each P2P bit on the Verizon network,As observed in,each P2P bit on the Verizon network traverses 1000 miles and takes 5.5 metro-hops on average,Second,there is a huge number of cross Internet service provider traffic,The studies showed that 50%-90%of the existing local pieces in active peers are downloaded externally.Third,the differences in playback time among peeers can be as high as 140s,and the lag can be greater if the source rate is higher,Fourth,most of the current P2P systems assume that all peers are willing to contribute their resources.however,this assumption may mot be true since the P2P systems are self-organizing networks and the peers are selfish by nature.Note that the selfish peers will act as free-riders if being free-riders can improve their utilities.译文:对等网络流:进化论的赛局的方法杨晨,学生;王蓓蓓,学生;塞布丽娜林,IEEE成员;永乐吴,学生;永乐刘,学生摘要:而对等网络视频流系统取得了很有前途,但这样的技术引进大量不必要的导线连接,从而导致实质性的网络无效率。

Unit 5 多址技术Unit 5-1第一部分:多址技术:频分多址、时分多址、码分多址多址方案用于使许多用户同时使用同一个固定带宽的无线电频谱。

在任何无线电系统中分配的带宽总是有限的。

移动电话系统的典型总带宽是50MHz ,它被分成两半用以提供系统的前向和反向连接。

任何无线网络为了提高用户容量都需要共享频谱。

频分多址(FDMA )、时分多址(TDMA )、码分多址(CDMA )是无线系统中由众多用户共享可用带宽的三种主要方法。

这些方法又有许多扩展和混合技术,例如正交频分复用(OFDM ),以及混合时分和频分多址系统。

不过要了解任何扩展技术首先要求对三种主要方法的理解。

频分多址在FDMA 中,可用带宽被分为许多个较窄的频带。

每一用户被分配一个独特的频带用于发送和接收。

在一次通话中其他用户不能使用同一频带。

每个用户分配到一个由基站到移动电话的前向信道以及一个返回基站的反向信道,每个信道都是一个单向连接。

在每个信道中传输信号是连续的,以便进行模拟通信。

FDMA 信道的带宽一般较小(30kHz ),每个信道只支持一个用户。

FDMA 作为大多数多信道系统的一部分用于初步分割分配到的宽频带。

将可用带宽分配给几个信道的情况见图5.1和图5.2。

时分多址TDMA 将可用频谱分成多个时隙,通过分配给每一个用户一个时隙以便在其中发送或接收。

图5.3显示如何以一种循环复用的方式把时隙分配给用户,每个用户每帧分得一个时隙。

TDMA 以缓冲和爆发方式发送数据。

因此每个信道的发射是不连续的。

待发送的输入数据在前一帧期间被缓存,在分配给该信道的时隙中以较高速率爆发式发送出去。

TDMA 不能直接传送模拟信号因为它需要使用缓冲,因而只能用于传输数字形式的数据。

由于通常发送速率很高,TDMA 会受到多径效应的影响。

这导致多径信号引起码间干扰。

TDMA 一般与FDMA 结合使用,将可用的全部带宽划分为若干信道。

这是为了减少每个信道上的用户数以便使用较低的数据速率。

Unit 4 通信和信息论Unit 4-1第一部分:远程通信远程通信是远距离通信的信号传输,在现代,通常这个过程需要电子发射机发射电磁波,但是在早期远程通信包括使用烟火信号,鼓或旗语或日光仪。

今天,远程通信很普遍的,助推这一过程的设备如电视,无线电和电话在世界的许多地区都已很普遍。

还有连接这些设备的许多网络,包括计算机网络,公共电话网,无线电网和电视网络。

互联网上的计算机通信是众多通信的一个例子。

通信系统通常由通信工程师设计。

在这个领域中早期的发明家有Alexander Graham Bell, Guglielmo Marconi 和John Logie Baird。

通信在当今的世界经济发展中起着举足轻重的作用,通信产业的税收在世界总产值的比例已接近百分之三。

基本要素每个通信系统包括三个基本要素:采集信息并能将其转换为信号的发射机,传输信号的传输媒介,接收信号并能将其还原为有用信息的接收机。

考虑一个无线电广播的例子。

广播塔是发射机,收音机是接收机,传输媒介是自由空间。

通常通信系统都是双向的,一个设备既做发射机又做接收机,即收发器。

例如,移动手机就是一个收发器。

电话线上的通信称为点对点通信,因为只在一个发射机和一个接收机之间。

通过无线电广播的通信称为广播(一对多)通信,因为通信是在一个大功率的发射机和许多接收机之间。

模拟或数字信号可以是模拟的,也可以是数字的。

在模拟信号中,信号根据信息而连续变化。

在数字信号信息被编码为一组离散值(如,1和0)。

在传输过程中,模拟信号中的信息会因噪声而退化。

相反,只要噪声不超过一定的阈值,数字信号中的信息是不会丢失的。

这是数字信号相对于模拟信号一个关键的优点。

网络网络是由一个相互通信的发射机、接收机或收发机的集合。

数字网络由一个或多个路由器组成,路由器正确地将数据发送给用户。

模拟网路由一个或多个交换器组成,交换器在两个或多个用户间建立连接。

这两种网络都需要中继器,用于远距离传输时的放大或重建信号。

Unit 8 光通信Unit 8-1第一部分:电磁频谱仔细研究表8.1中的频率表可以看到各种用于信息传输的光学技术的潜力。

人们所感兴趣的“现代”常规通信系统的信息传播速率通常相应于电话系统中的音频、商用广播系统中的无线电频率、或是最先进的视频节目分配系统中的数字电视数据率。

这些数据率通常低于几个吉赫兹(GHz)。

如果传输这样的信息不是将它加载到光纤上,而是加载在略高于最大速率的射频载波上,则此射频载波就会是厘米波或是波长更长一些的波。

用光载波则有很大的优越性。

一个明显的优点就是光纤的低损耗和方向性。

载波的数据率显然必须高于信息速率。

通信系统的一个基本原则是频率愈高,技术就愈复杂。

处理微波就比处理无线电波更困难。

随着波长减小到接近于电路元件的尺寸,电路单元就不再是集总的,导线可起到反射元件以及(或)天线的作用,集总单元则成为电磁谐振器。

这通常意味着当发送的信息较多时,代价也较高,因此在较高的信息率要求较高的频率这层意义上,要考虑传输信息的每个bps的成本问题。

于是,观察上述频率表得到的第一个结论就是,对于频率为数百特赫兹(THz)的光载波而言,信息的带宽在某种意义上是免费的。

就是说与大多数器件相比,光的波长是如此之小,以至于所用技术与电和微波有根本的不同。

一旦我们具备了这样的技术,则无论信息率有多高,再也没有必要改变载波了,因为载波频率高于任何现实信息率所能达到的程度。

不过带宽也不是完全免费的,因为编码器和解码器必须工作在相应于信息率的频率上,而系统其余部分大都只需要处理载波和调制。

如果一个元件可以工作在5⨯1014Hz的频率上,在这个频率信息偏移千分之一(相应于500吉赫兹的信息率)对器件的性能将没有什么影响。

因此,只要系统已经建立起来,大体上就可以随意升级系统而不会涉及常规系统中改变电磁载波所需付出的那种代价。

光波的宽频带一个结果就是光载波可以同时携带许多不同电话信号和电视节目等。

通常实现这种同时传输多路信息的过程(至少以同步格式实现)称为时分复用。

专业外语综合阅读与翻译报告学院:信息电子技术学院专业:电子信息工程班级:一班学籍号:********姓名:******成绩:2016年5月20日英文原文:With all the exciting developments in the realm of communications technology over the last few years it would be easy to think that we are living in times of the most astounding transformations. However, the technologies that so many of us are addicted to today mobile phones, the internet, satellite TV are built on the achievements of our endeavors. The history of communication goes back thousands of years. Each new development has transformed the world we live in. An understanding of the journey we have taken to get where we are now shows that today’s techniques are refinements of what came before. Really big revolutions may be still to come.communication begins with the first conversations between people it is believed that language developed through gestures using the hands and bodies, and had evolved into spoken tongues by the time of the great migration of humans from Africa some 100,000 years ago.The first long distance communication must have arisen shortly after conversation, with the discovery that it was possible to make oneself heard from a distance by shouting, or banging objects together to make a sound that travels far. The fire and the smoke it produces may also have been used for simple communication between separated groups.Communication techniques such as shouting and smoke signals allow people to make their mark over a wider area. The recording of information allowed human beings to communicate over great expanses of time. Cave paintings up to 36,500 years old have been found people from that far back are communicating with us today although it is hard to know what they were saying. 5,500 years ago, more systematized alphabets were developed by the Phoenicians. Sumerians and Egyptians. They also developed new ways of storing their information, some of which have survived till today. Scholars have had some success in translating these alphabets and the languages they convey, giving us insight into societies long dead.The realisations that it is possible to communicate through space and time are the two most important communication leaps in history. Everything that has come since has merely improved the efficiency of these two tasks.The next leap was the combination of writing and transmitting information. This begin with people or animals acting as couriers, delivering written messages. The first postal services were in China around 900BC. Human runners and birds were used to transport messages starting in at least 776BC, when the winner of the Olympic games was reported to the Athenians via homing pigeons possible the first journalist reporting back to base from a remote location.With the discovery of electricity the speed and range of communication once again began to increase. In 1793 Claude Chappe invented the Semaphore telegraph line, which allowed reliableand fast communication over wires between distant locations. Methods such as the Heliograph which require two locations being able to see each other limited the possible distance of rapid communications. The semaphore broke through this barrier, opening the way for even more radical developments.The invention of techniques such as Morse code allowed complex messages to be transferred at very high speeds over this new medium. This had huge repercussions for many aspects of human life – transport could be better coordinated, government could transmit decisions to distant offices almost instantaneously, businesses could work with more businesses over large distances.With Joseph Henry’s invention of the telegraph in 1831 developments took on a cheetah like speed – with thirty years wires were strung around and between many countries in the world. At first these were used to transmit simple signals in the form of short and long beeps – Morse code. Shortly after this, in 1843, Alexander Bain developed the chemical telegraph –a machine that enabled messages written on paper to be copied onto another machine a long distance away – the first Fax machine! Nearly twenty years later Alexander Graham Bell patented the electric telephone. This enabled people with no training to communicate in the most natural form speaking even when separated by hundreds of miles. The first telephone conversation was between bell and his assistant, Watson-Mr. Watson, come here, I want you! These words changed the world forever.Over 45 years the limit of how fast people could communicate had gone from the speed of the fastest form of transport, to the speed that signals could travel down an electric wire –the speed of light! These developments made it possible to communicate efficiently over much larger distances, changing social lives, government, military operations, investments, agriculture, almost everything.We saw how the storage of communication in the form of writing was a leap that permitted people to communicate through time as well as space. Shortly after the invention of thetelephone, the storage of sound became possible. In 1877 Tomas Edison patented the phonograph, which used wax cylinders to record sound. Ten years later the invention of gramophone made it possible for sound recordings to last much longer – early recordings made over 100 years ago can still be listened to today.The technologies that I have discussed in these articles have all helped us store and transmit communication. All these technologies are joining together in the form of computers and the internet. A cheap computer connected to the internet gives a person access to storage and transmission of wireless words, sounds, and images both still and moving. The future will see this convergence grow, with mobile computers allowing us to take photographs and send them to our friends instantly, wherever they are.Eventually we may even combine ourselves with our mobile computers, and transmit our thoughts and experiences directly into the heads of other people. Communication is after all about sharing experience.阅读翻译:随着通信技术在过去几年中所有令人兴奋的领域中的发展,这将是很容易认为我们正生活在一个最令人震惊的时代转换。
