Advanced Communication Systems

This book presents an in-depth treatment of both the theoretical and applied aspects of modern communication systems. It provides a solid mathematical foundation, including stochastic processes, information theory, and signal analysis, which are essential for understanding system performance and design. The book thoroughly covers analog and digital modulation techniques, channel coding methods, and the modeling of wireless, optical, and wired communication channels. Special emphasis is placed on emerging technologies such as MIMO systems, fifth-generation (5G) and beyond wireless networks, and future communication paradigms driven by high spectral efficiency, reliability, and intelligent networking. Intended for advanced undergraduate and graduate students, researchers, and practicing engineers, this book serves as a comprehensive reference for the analysis and design of next-generation communication systems.
