This book provides the analytical tools to characterize nonlinear distorted multicarrier signals and optimal/sub-optimal receivers employed in high data rate communication systems. Unified Theoretical Analysis of Nonlinear Multicarrier Schemes introduces new optimal and sub-optimal receivers for nonlinear distorted signals that can use nonlinear distortion to improve performance when compared with common receivers. It addresses the analysis of nonlinear systems with stochastic inputs and establishes new receivers designs for multi-carrier communication systems with nonlinearities. The authors also include the characterization and definition of optimum and sub-optimum receivers for nonlinear distorted signals that may use the nonlinear distortion to improve receiver performance over the existing ones. The book also includes a set of applications where the analytical unified method for characterization of nonlinear distortion can be applied. The two final chapters of the book include systems like MIMO OFDM and the extension to optical systems. These techniques are the base of 5G, Wi-fi and future 6G mobile networks. The book will be a valuable resource for design engineers, industrial engineers, applications engineers and researchers working on multi-carrier systems, power amplifiers modelling and design.

This book explores the evolution of artificial intelligence (AI) and its wide-ranging impacts. Beginning with the concept of the silent economy, this work traces the development of AI from its early stages to the present, highlighting the emergence of generative AI. The narrative examines how AI influences organizational culture, societal well-being, and business decisions at strategic, tactical, and operational levels. The book also analyzes the evolving dynamics of the workplace, consumer behavior, and AI's ethical and legal implications. The final chapter offers thoughtful reflections on future generations of AI, presenting a comprehensive and insightful perspective on this transformative technology.
