• Focus: Fundamentals of digital communication systems — theory and practical techniques for transmitting discrete (digital) information over physical channels.
• Target audience: Upper-level undergraduates, graduate students, and practicing engineers with background in signals, probability, and linear systems.
• Typical scope: Source coding, channel coding, modulation, detection, synchronization, channel models, performance analysis, and practical system considerations.

1. Check your university library portal first. If you are enrolled, the PDF is likely waiting for you legally.
2. If you are not a student: Purchase the e-book chapter-by-chapter via Elsevier or Google Play Books. It is cheaper than a pizza and will last your entire career.
3. Avoid the pirate sites. The risk of malware and the guilt of stealing from an author who wrote the book to simplify your life are not worth the $70 you save.
