Features: This textbook is designed for the course teaching of Electronic and Information Technology in higher vocational education or as a foundational course for Communication Technology. Students using this textbook should have some knowledge of electronic circuits and the principles of electronic devices. The objective of this course is to help students establish a comprehensive understanding of digital communication systems, learn general methods of digital signal transmission and processing, understand the composition and working principles of satellite communication systems, optical fiber communication systems, and mobile communication systems. Students will also gain insights into the composition and operational characteristics of common communication networks such as computer local area networks, digital data networks, and mobile communication networks. Additionally, they will learn about the content and applications of communication protocols like OSI, modern communication technologies, and lay a foundation for further specialized studies in communication. The course also aims to cultivate students' ability to systematically analyze problems.
This book focuses on introducing the characteristics of digital signals, the basic principles of baseband and bandpass transmission, methods of source, channel encoding and decoding, the composition and working principles of various digital transmission systems. It also provides a brief introduction to the composition and working principles of some digital communication networks, including computer local area networks, mobile communication networks, integrated services digital networks, and packet-switching networks.
The content of this book is easy to understand and covers a wide range of knowledge, requiring relatively low professional foundation from readers. It is suitable for students in higher vocational education institutions and can also serve as a reference book for electronic engineering technicians and management personnel.
