Principles Of Digital Communication, published in the year 2009, comprehensively covers the basics of this subject. Digital communication means point-to-point or point-to-multipoint physical transfer of data. To truly understand this channel of communication, the author believes that it is important to focus on the basic principles of modern digital communication, instead of just the commonly used hardware and software systems.
This text uses lucid language and a simple framework to explain each topic. Proofs are provided so that students can understand every digital system thoroughly and intuitively. Furthermore, practical applications have been weaved into the theory. This plays an important role in establishing strong links between the two and helps students grasp the concepts clearly.
Principles Of Digital Communication splits up the theoretical principles into two parts. The first section focuses on analytical tools that help figure out the performance levels of particular systems. The second section introduces students to the limitations of every system. Instead of taking specific examples, Gallager has used simple models and approximations that are applicable to general systems.
The first chapter is an introduction to digital communication. This is followed by chapters like Coding for Discrete Sources, Quantization, Source and Channel Waveforms, Vector Spaces and Signal Space, Channels, and Modulation and Demodulation. Some of the other chapters are Random Processes and Noise, Detection, Coding And Decoding, and Wireless Digital Communication.
Readers are introduced to data compression for arbitrary sources, CDMA, and how to modulate binary data. The book is packed with various types of exercises. Some show how the breakdown of analysis takes place when restrictions are violated. Some others concentrate on how theoretical concepts are used in practical problems.
A combination of theory and applications makes Principles Of Digital Communication a very useful guide. It has been designed for graduates, to be taught during the course of one semester.
