While written decades ago, the foundational theory in this book remains unchanged. Modern wireless communication systems—such as 5G networks, Wi-Fi protocols, and satellite links—still rely on the core modulation, coding, and noise theories outlined by Shanmugam. Understanding these analog fundamentals is essential for designing modern digital architectures. 5. Finding the PDF and Academic Resources

It does not skip steps in derivations, making it excellent for self-study.
If you are currently studying from this textbook or designing a communication system, let me know:
For mathematics equations use $$ syntax without newlines, for example, Shannon's channel capacity equation for analog communication is $$C = B \log_2 (1 + \fracSN)$$.
Given that the book was first published in 1979, many students and professionals today seek a digital copy.
