Digital Communication A Simplified Approach

This book is designed to serve as a text for senior undergraduate level students in electronics and communication, and telecommunication engineering. It is as well designed to serve as a text for self study and reference book for practicing engineers working in the field of digital communications. The main objective of penning this book has been to make learning intricate concepts a pleasant experience. Features Integrated with Figures and diagrams in abundance, Plentiful worked examples, Lots of exercise problems with answers. Basic principles of Fourier transform have been discussed. Basic properties of Probability and Random Processes have been discussed to characterise random signals and noise. An introduction discussing the building blocks of digital communication system has been added to prepare the student before diving deep into the subject. Matched filters and correlators are discussed step by step with relevant signal constellation diagrams showing the decision boundaries with emphasis on understanding the concept of detection and estimation as foundation. Different types of sampling, multiplexing and reconstruction techniques have been discussed to understand the link between analog and digital world. Generation, transmission and regeneration of signals using PCM and other coding techniques have been discussed in depth. Different types of line coding schemes and effect of noise have been discussed before proceeding to digital modulation schemes. Various digital modulation schemes have been discussed along with diagrams and importance is given to probability of error calculation. Principle of spread-spectrum modulation, its advantages and applications are discussed.
