Crucially, the book builds digital communication systems using discrete-time signal processing from the start. This aligns perfectly with how modern systems are actually implemented: using DSP chips, FPGAs, and ASICs. If you want to write code for a modem, this is your text.

A recurring theme in the text is the hostile nature of the channel. Real-world channels have limited bandwidth, causing pulses to spread out and bleed into one another—a phenomenon known as .

To help you get the most out of this textbook or your coursework, tell me a bit more about what you are working on: The book provides exhaustive coverage of linear modulation

John R. Barry's book, "Digital Communication," is a comprehensive guide that covers the fundamental principles and techniques of digital communication. The book provides an in-depth analysis of the subject, including the basics of digital communication, channel capacity, modulation, coding, and communication networks. The book is widely used as a textbook in universities and colleges, as well as a reference book for professionals in the field.

Most university systems provide authenticated students with digital proxy access to the full ebook text.

In real-world systems, transmitter and receiver clocks are never perfectly aligned. Barry devotes significant attention to the synchronization sub-systems required to make digital communication viable.

Adding redundancy to detect and correct transmission errors.
