The open access book covers a large class of nonlinear systems with many practical engineering applications. The approach is based on the extension of linear systems theory using the Volterra series. In contrast to the few existing treatments, our approach highlights the algebraic structure underlying such systems and is based on Schwartz’s distributions (rather than functions). The use of di…
This open access book from the world’s first 6G Flagship research program at the University of Oulu, Finland, provides a multi-disciplinary and insightful overview of the subject, with contributions from experts in the field. Today’s fourth generation of mobile connectivity services (4G) are available everywhere, and adoption of fifth generation (5G) networks is well underway. Compared to 4…

Ultrawideband phased array antennas are an enabling technology for many ground-based and airborne communications and radar systems. This book surveys electromagnetic theory and phased array antenna theory and provides examples of ultrawideband phased array antenna technology. It describes some of the research on ultrawideband phased arrays undertaken by the authors and their colleagues at MIT L…
"Why do we feel insulted or exasperated when our friends and family don't answer their mobile phones? If the Internet has allowed us to broaden our social world into a virtual friend-net, the mobile phone is an instrument of a more intimate social sphere. The mobile phone provides a taken-for-granted link to the people to whom we are closest; when we are without it, social and domestic disarray…
"Wireless networks are the fastest growing communications technology in history. Are mobile phones expressions of identity, fashionable gadgets, tools for life - or all of the above? Mobile Communication and Society looks at how the possibility of multimodal communication from anywhere to anywhere at any time affects everyday life at home, at work, and at school, and raises broader concerns abo…
This book offers an accessible introduction and practical guide to Voice over Internet Protocol (VoIP) technology, providing readers with the know-how to solve the problems encountered in applying VoIP technology across all types of network. It incorporates the latest research findings and brings readers up to date with the challenges that are faced by researchers developing novel applications …
This book presents the fundamental concepts, recent advancements, and opportunities for future research in various key enabling technologies in next-generation wireless communications. The book serves as a comprehensive source of information in all areas of wireless communications with a particular emphasis on physical (PHY) layer techniques related to 5G wireless systems and beyond. In particu…
This book provides a broad understanding of the fundamental tools and methods from information theory and mathematical programming, as well as specific applications in 6G and beyond system designs. The contents focus on not only both theories but also their intersection in 6G. Motivations are from the multitude of new developments which will arise once 6G systems integrate new communication net…
