All-Digital RF Transmitters for Next Generation Wireless Communications

This book introduces the foundations of All-Digital Transmitters (ADTs), namely Delta-Sigma Modulation and Pulse-Width Modulation, and then focuses on the main research challenges and achievements that have been reported.Architectures are presented for specific cases, along with low-level diagrams and implementation figures of merit. All-Digital RF Transmitters for Next Generation Communications presents a broad, in-depth view of the technology and the challenges it faces.The authors present a set of ideas and architectures that enable the implementation of fully digital transmitters, bringing the digital domain closer to the antenna.In each chapter the reader is presented with a set of challenges that are paired with theoretical explanations and experimental validations of how the problem was overcome.In particular, the authors begin with the analog filtering requirements from the reconstruction filter, carrier agility, architectural techniques for designing wideband and high-speed de
