通信工程专业英语教程
通信工程专业英语教程The field of communication engineering has experienced remarkable advancements in recent years, driven by the rapid technological progress and the ever-increasing demand for efficient and reliable communication systems. As the world becomes more interconnected, the role of communication engineers in shaping the future of global communication networks has become increasingly crucial. To meet the evolving needs of this dynamic industry, the development of a comprehensive and well-structured English curriculum for communication engineering majors is of paramount importance.The primary objective of an English curriculum for communication engineering students should be to equip them with the necessary language skills and technical knowledge to effectively navigate the global landscape of communication technologies. This curriculum should be designed to not only enhance their proficiency in English but also to provide them with a deep understanding of the specialized terminology, concepts, and methodologies relevant to their field of study.One of the core components of such a curriculum should be a strong emphasis on technical writing and communication. Communication engineers are often required to prepare technical reports, proposals, and presentations, which necessitate the ability to convey complex information in a clear, concise, and professional manner. The English curriculum should therefore include courses that focus on technical writing, report writing, and professional communication, providing students with the opportunity to develop these essential skills.In addition to technical writing, the curriculum should also incorporate language training that caters to the specific needs of communication engineers. This may include courses on academic English, scientific and engineering English, as well as English for specific purposes (ESP) courses that cover topics such as telecommunication systems, signal processing, and network protocols. By providing students with a solid foundation in the language used in their field, they will be better equipped to engage in discussions, read and comprehend technical literature, and collaborate with international colleagues.Another crucial aspect of the English curriculum for communication engineering majors should be the integration of project-based learning. This approach allows students to apply their language and technical skills in real-world scenarios, fostering their ability to work in teams, solve complex problems, and communicate effectively withdiverse stakeholders. Such projects may involve the design and implementation of communication systems, the analysis of network performance, or the development of innovative communication technologies.Furthermore, the curriculum should incorporate opportunities for students to engage in international collaborations and exchanges. This could include student exchange programs, virtual international team projects, or participation in global communication engineering conferences and workshops. These experiences not only enhance students' language proficiency but also expose them to different cultural perspectives and industry practices, preparing them for the global nature of the communication engineering field.To ensure the effectiveness of the English curriculum, it is essential to incorporate ongoing assessment and feedback mechanisms. This may include regular evaluations of students' language proficiency, technical knowledge, and communication skills, as well as feedback from industry partners and alumni to ensure the curriculum remains relevant and responsive to the evolving needs of the communication engineering sector.In conclusion, the development of a comprehensive English curriculum for communication engineering majors is a crucial step in preparing the next generation of communication professionals. Bycombining language instruction with technical knowledge and practical application, this curriculum will equip students with the necessary skills and competencies to thrive in the dynamic and globally interconnected world of communication engineering. As the demand for efficient and innovative communication systems continues to grow, the importance of a well-designed English curriculum cannot be overstated, as it will contribute to the development of highly skilled and globally-minded communication engineers who can drive the future of the industry.。

Ancient systems and optical telegraphy
Early telecommunications included smoke signals and drums. Talking drums1 were used by natives in Africa, New Guinea and South America, and smoke signals in North America and China. Contrary to what one might think, these systems were often used to do more than merely announce the presence of a military camp.
Telephone
The electric telephone was invented in the 1870s; it was based on earlier work with harmonic (multi-signal) telegraphs. The first commercial telephone services were set up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Alexander Graham Bell held the master patent for the telephone that was needed for such services in both countries. All other patents for electric telephone devices and features flowed from this master patent.

The internet is the largest repository of information which can provide very large network resources.5、开发蜂窝式移动电话系统并将其在许多城市中推广应用的原因之一是传统的移动电话系统存在容量有限、服务性能差、频谱利用率低的缺点。
One of many reasons for developing a cellular mobile telephone system and deploying it in many cities is the operational limitations of conventional mobile telephone system; limited servile capability，poor service performance，and inefficient frequency spectrum utilization.6、来自发端借口不见的定时新号被加到数据调制解调器上，以使计算机与数传机同步。
在接收端，从数据流中取出同步脉冲式计算机同步。
Timing signals from the interface assembly at the transmitter are applied to the data modem to synchronize the computer and the data set. At the receivers synchronization pulses are derived from the data stream to synchronize the computer.7、我们正处于通信网络革命的开始，越来越大的容量需求，各种各样的应用，以及服务质量正在对光网络提出巨大的需求。
We are at the beginning of a revolution in communications networks, where increasing capacity, variety of applications, and quality of service are placing enormous demands on the optical network.8、目前在欧洲正在开发第三代移动通信系统，其目的是要综合第二代系统的所有不同业务并覆盖更广泛的业务（话音、数据、视频、多媒体）范围，而且还要与固定电话网络的技术发展保持一致和兼容。
The third generation mobile communication system currently being developed in Europe, intended to integrate all the different services of the second generation system and cover a much wider range of broadband services (Voice、data、video、multimedia)consistent and compatible with technology developments taking place within the fixed telecommunication networks.9、在现代对多媒体的描述中，我们所具有的技术已开始向人类具有的能力迈进；通过使用计算机技术、软件和其他技术，如CD-ROM。
不仅能将视频图像和音频综合在一起，而且可以与其他计算机用户进行交互工作。
In the modern presentation multimedia we now have the technology that can begin to move towards an ability already held by the human beings in that by using computer, technology, software and other technology, such as CD-ROM not only can we bring together audio and visual images but interactive with other computer users.10、为弥补这些问题，要在基本结构中加入大量的高效中继线。
高效中继线用于直接连接有大量的节点间通信业务量的各交换中心。
通信量常常是通过网络中可用的最低层次传送的。
To compensate for these problems, a large number of high usage trunks augment the basic architecture. High-usage trunks are used for direct connection between switching centers with high volumes of internodes traffic. Traffic is always routed through the lowest available level of the work.11、光纤网络的革命刚刚开始，并正快速向未来的带宽无线、可靠和低费用的在线世界发展。
