Dr. Ali Grami holds a PhD in Electrical Engineering from the University of Toronto. His background includes pioneering work at Nortel Networks on North America's first digital cellular system and lead research for Canada's Anik-F2, the world's first broadband access satellite system. This industry experience ensures the textbook is not just theoretical but grounded in practical engineering challenges. Introduction to Digital Communications | ScienceDirect
Here are the key features and details about the book and the PDF version:
| Best for | ✅ Senior undergrads / early grad students in EE/CE
| | ✅ Self-learners with solid math (calculus, probability, linear algebra)
| | ✅ Instructors looking for a compact, no-nonsense text for a one-semester course
| Not ideal for | ❌ Absolute beginners to signals/probability
| | ❌ Practitioners needing deep coverage of MIMO, 5G, or optical communications
| | ❌ Those wanting many practical circuit or system design examples
Given Eb/N0 (linear) = γb, BPSK BER = Q(√(2γb)). If Eb/N0 = 10 dB → γb = 10 → BER ≈ Q(√20) ≈ Q(4.472) ≈ 3.9×10^−6.
Digital communications integrates signal processing, probability, coding, and hardware constraints to reliably transmit information over imperfect channels. Mastery requires both theoretical understanding (information theory, detection theory) and practical skills (simulation and implementation).
