Introduction

Digital communication transforms information into discrete symbols for efficient, robust, and secure transmission across noisy channels. Building on Shannon’s information theory and advances in signal processing, the field addresses the tradeoffs among data rate, reliability, spectral efficiency, and complexity. John R. Barry’s contributions, situated within communications engineering literature, emphasize modulation/demodulation, coding, synchronization, channel modeling, and practical system design.
