Communications System (PLT 208/3)

"Digital Communications" presents the theory and application of the philosophy of Digital Communication systems in a unique but lucid form. The book inserts equal importance to the theory and application aspect of the subject whereby the authors selected a wide class of problems.The Salient features of the book are:1. The foundation of Fourier series, Transform and wavelets are introduces in a unique way but in lucid language.2. The application area is rich and resemblance to the present trend of research, as we are attached with those areas professionally.3. Elegant exercise section is designed in such a way that, the readers can get the flavor of the subject and get attracted towards the future scopes of the subject.4. Unparallel tabular, flow chart based and pictorial methodology description will be there for sustained impression of the proposed design/algorithms in mind.

Principles of Digital Communication Systems & Computer Networks is designed as a textbook for digital communication systems, data communication and computer networks, and mobile computing. Part I deals with key topics such as information theory, transmission media, coding, error correction, multiplexing, multiple access, carrier modulation, PSTN, and radio communication. Part II goes on to cover the networking concepts, the ISO/OSI protocol architecture, Ethernet LAN, X.25 protocol, and TCP/IP protocol. Finally, Part III covers mobile computing, including radio paging, cellular mobile, GPS, CTI, unified messaging, and multimedia communication. Helpful summaries, lists of supplementary information, references, and exercises at the end of each chapter make the book a comprehensive resource for anyone pursuing a career in telecommunications and data communication.

Addressing the fundamental technologies and theories associated with designing complex communications systems and networks, Principles of Communications Networks and Systems provides models and analytical methods for evaluating their performance. Including both the physical layer (digital transmission and modulation) and networking topics, the quality of service concepts belonging to the different layers of the protocol stack are interrelated to form a comprehensive picture. The book is designed to present the material in an accessible but rigorous manner. It jointly addresses networking and transmission aspects following a unified approach and using a bottom up style of presentation, starting from requirements on transmission links all the way up to the corresponding quality of service at network and application layers. The focus is on presenting the material in an integrated and systematic fashion so that students will have a clear view of all the principal aspects and of how they interconnect with each other. A comprehensive introduction to communications systems and networks, addressing both network and transmission topics Structured for effective learning, with basic principles and technologies being introduced before more advanced ones are explained Features examples of existing systems and recent standards as well as advanced digital modulation techniques such as CDMA and OFDM Contains tools to help the reader in the design and performance analysis of modern communications systems Provides problems at the end of each chapter, with answers on an accompanying website
