INSTRUCTION ON THE SECOND EDITION The first edition of this textbook has been published for 5 years. It is the time to revise it. In addition to error correction and improvement on description, the main differences between the second edition and the first edition are as follows. In recent years, the technology on telecommunication networks has developed rapidly. Many new networking technologies and new network functions emerge endlessly, especially in the field of wireless vehicle communication. Today, cellular vehicle communication network with 4G performance has been spread extensively in China and Wi-Fi has benefited most of the notebook computer and mobile phone users. Bluetooth, RFID, GPS, and NFC are used more and more popular. Those new developed technologies and applications can’t be included in a textbook which is belonging to the scope of fundamental principle of communication. On the other hand, some old networking technologies are gradually declined, such as ISDN, ATM, and so forth. Hence, the chapter on communication networks in the first edition is deleted. Along with the capacity of communication system increasing and the communication channel rapidly digitizing, multimedia communication has been extensively used. Multimedia technology is closely relevant to source compression coding which includes speech compression coding, image compression coding and digital data compression coding. So, the contents on source compression coding are enhanced in the second edition, and the contents on information theory are reduced. Preface In recent years，communication theory and technology has witnessed rapid development. In China，the application of telecommunication service has penetrated into almost every household and every person. The huge modern communication networks have been one of the important infrastructures in China. Correspondingly，the amount of telecommunication enterprises and employees there has also been increasing remarkably. Under this situation，the education of the new specialized personnel in the telecommunication field and the reeducation of the personnel in service have become important tasks. In addition，bilingual teaching is a new requirement in Chinese institutions of higher learning，and its importance has been recognized by more and more people. However，there is lack of appropriate textbooks in English on communication theory for Chinese students. This textbook is intended to accommodate the demand. The current communication networks in China have almost all been digitized. Signals transmitted in China’s public communication networks are mainly digital ones;only the signals transmitted in the user’s loop and those signals for special applications are still analog. Hence，the discussion of analog signal transmission techniques is limited to a minimum，and the greater part of this book is devoted to discussions of digital communication including transforming，encoding and transmission of digital signals，as well as the digitization of analog signals. In the discussion on digital communication technology，some new communication technologies have been emphasized，for example，trellis code modulation (TCM)，orthogonal frequency division modulation (OFDM)，multiple access，spread spectrum，TURBO code，and so on. Attention has been directed to the explanations that are associated with the application examples of the currently rapidly developed networks，such as satellite communication and computer communication networks，and so on. In order to best possibly meet the teaching demand in different universities and the demand of the readers who are in active service，this book is divided into two parts. The first part constitutes the basic contents，and is essential for beginners. The second part contains the optional contents，and each chapter in this part is relatively independent. Some chapters in the second part can be selected for learning depending on teaching requirements，some of which can be used as reference for communication engineering personnel. In addition，considering the demands of different teaching programs and different teaching periods，some contents that have complicated calculations or proofs are printed under shadow. Those parts can be skipped over，without affecting understanding of the content that follows. Questions and exercises are provided at the end of each chapter. The questions can be used for review of the contents of each chapter，and can aid the readers in making a brief summary of the contents of each chapter by themselves. The exercises allow the readers to deeply grasp the contents of each chapter，to combine the theory with the practice，and to improve their ability to solve practical problems. There are also some references at the end of this book for the readers to find the origins of the relevant conclusions. There are no more references listed，because during the network information era，the readers can easily obtain their required information from the Internet. There are 7 chapters in the first part. The first chapter is focused on the introduction of communication，especially the basic concepts of digital communication and channels，and helps the readers build up a preliminary understanding. The second chapter elaborates on the characteristics of signals and the influence of channels on the transmission of signals. The third chapter briefly dwells on the principles of analog modulation systems. The fourth chapter discusses the sampling，quantization，and encoding methods of analog signals in detail. The fifth chapter gives a basic introduction of every aspect of the design of baseband transmission systems. The sixth chapter discusses the basic digital modulation systems in detail. The seventh chapter discusses synchronization including carrier synchronization，bit synchronization，group synchronization，and network synchronization，which is absolutely necessary for digital communication systems. The second part consists of 7 chapters in total. The eighth chapter discusses the ideal performance of the system from the viewpoint of the optimum reception of digital signals，and the comparison of the optimum reception with that of the practical systems. The ninth chapter describes multichannel multiplexing and multiple access;specifically introducing some relevant international recommendations for the standards and some practical systems. The tenth chapter discusses error correcting coding and error control technology;the principles of error correcting coding with fine performance are emphasized. The eleventh chapter thoroughly discusses advanced digital modulation technologies on the basis of Chapter 6. The twelfth chapter describes the information theory. The performances of communication systems are analyzed using the fundamental theory in order to search for the optimum source coding methods and the optimum performances of the communication systems. The thirteenth chapter introduces various communication networks including telephone networks，data communication networks，integrated services digital networks and vehicle communication networks. The fourteenth chapter briefly introduces the principles of cryptography. Each chapter in Part 2 is relatively independent. Part 2 can be optionally studied based on demand，and its understanding will not be affected by skipping over some chapters (There is certain connection only between the Viterbi decoding algorithm in Chapter 10 and the TCM in Chapter 11.) For the junior and senior students of general higher education institutions，lectures may be between 36 to 90 hours (or 2 to 5 credits) according to different specialties and different universities. The course may be arranged within one or two semesters，and supplemented by experiments. The prerequisites for studying this book are mainly： analog electronic circuits，high frequency electronic circuits，digital logic circuits，linear algebra，probability theory，as well as signals and systems. For the students who have studied the course "Signals and Systems," the second chapter of this book may be briefly introduced as a review or just skipped over.
