5G, a new generation of
cellular technology under deployment worldwide, can provide about 100 times
faster communications than current 4G technology. But a higher speed is not the
sole differentiating factor: 5G is also more reliable, secure, and capable of
ubiquitously connecting a massively large number of devices. Ultra-reliable,
low-delay, omni-present 5G networks hold the promise of enabling a range of new
applications, including self-driving cars, highly automatized industrial tasks,
virtual reality gaming, as well as of providing the connectivity platform for
the Internet of Things (IoT).
Since its introduction
in 1948, information theory has underpinned the mathematical foundations of
communication systems, including 5G networks, and it will impact the design of
cellular systems beyond 5G. The theoretical insights obtained by information
theory point to the optimal system performance under a given model, offering
strong guidelines and benchmarks for the design and validation of modern
communication technologies.
Information
Theoretic Perspectives on 5G Systems and Beyond provides a comprehensive overview of the
state-of-art information-theoretic approaches that led to realization of 5G.
Three main areas are discussed, namely network architecture, coding and
modulation, and network protocols. Examples of covered topics include cloud/fog
radio access networks (a central component in future 6G (beyond 5G) cell-less
structure), device-to-device communications, caching, energy harvesting, polar
coding, Massive MIMO, short-packet transmission, NOMA, 5G protocols,
interference management, content delivery, and cooperative and confidential
communications.
Information Theoretic Perspectives on 5G Systems and Beyond is the result of a grand effort by more than 40 experts in the field of information theory. It includes 19 chapters, offering a detailed introduction to advanced topics in information theory, and it took several years in making. We are extremely excited that the book is now available. We hope that it can serve as a tool for researchers and graduate students in the fields of information theory and wireless communications, as well as for practitioners in the telecommunications industry.
