Introduction to Digital Communications

Introduction to Digital Communications, 2nd Edition provides a systematic academic textbook examining core principles for analyzing and designing digital communication systems. Author Ali Grami focuses on how engineering parameters, primary design objectives, physical constraints, and operational trade-offs shape modern transmission channels.

The text develops theoretical and practical concepts through structured coverage themes. Early sections address signals, systems, spectral analysis, probability, and random processes before transitioning into analog-to-digital conversion, digital baseband transmission, and digital passband transmission. The material further examines key system components, including synchronization, information theory, error-control coding, source coding, and network architecture.

The textbook is structured to support upper-division undergraduate curricula for third-year and fourth-year electrical, computer, and software engineering students, as well as foundational coursework for first-year graduate students. Beyond the classroom, the text offers technical context for practicing engineers, project leaders, and technical supervisors responsible for managing digital communication infrastructure.
