Principles of Digital Communication

This book aims at the delivery of the content in a lucid manner; builds the understanding level of the reader in a well-structured manner and thus will be very good resource in the area of Digital Communication. It will be a one point contact for all the contents of the course on Digital Communication as per the prescribed syllabus for B.Tech (Electronics and Communication Engineering.) in many universities across the country.      All the concepts discussed in theory are well established through a good number of numerical examples. The book enables the reader to attempt various question of Higher Order Thinking with confidence, in the proposed area. To provide a good insight for the subject, the concept discussed are validated through Matlab/Scilab simulations.             This Book will be an excellent aid for the students preparing for various national level competitive Examinations in Engineering (ECE stream). Questions (including short answer questions) from previous such examinations are provided at the end of each chapter along with solutions. Contents: 1. Introduction to a Digital Communication System2. Some Random Variables3. Sampling Theorem4. Analog to Digital Conversion5. Bandpass Digital Communication6. Baseband Signal Receiver7. Noise Performance of Digital Modulation Schemes8. Information Theory9. Source Coding About the Author: Dr. Piratla Srihari received Ph.D in the stream of Electronics and Communication Engineering  from Jawaharlal Nehru Technological University, Hyderabad .He is in teaching since more than 3 decades.
