This book is aimed at the Undergraduate course on Digital Communications. Written from the perspective of geometrical representation of signals, the book lays emphasis on clarifying concepts from the fundamental level.

• Systems approach to Digital Communication right at the foundational level.



• Covers digital modulation based on signal space concepts.



• Optimization between the bandwidth efficiency and power efficiency of a communication system.

‘The section on information theory and entropy is very good.’

‘The author has brought in sharper focus towards the state-of-the-art technology indicating the application of mathematical tooling in the context of relevance of the present day needs’
