This book focuses on elementary concepts of both radio frequency energy harvesting (RFEH) and wireless power transfer (WPT), and highlights their fundamental requirements followed by recent advancements. It provides a systematic overview of the key components required for RFEH and WPT applications and also comprehensively introduces the pioneering research advancements achieved to date. The state-of-the-art circuit design topologies for the two different applications are presented mainly in terms of antenna operating frequencies, polarization characteristics, efficient matching network circuits, rectifier topologies, and overall rectenna systems. The book serves as a single point of reference for practicing engineers and researchers searching for potential sources and elements involved in the RFEH system as well as in the WPT system, and need rapid training and design guidelines in the following areas: • Different sensing elements used in RFEH and WPT • Inclusions of mathematical expressions and design problems • Illustration of some design examples and performance enhancement techniques

Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.

Using a systems framework, this textbook clearly explains how individual elements contribute to the overall performance of a radio system.

Over the last few decades, the radio documentary has developed into a strikingly vibrant form of creative expression. Millions of listeners hear arresting, intimate storytelling from an ever-widening array of producers on programs including This American Life, StoryCorps, and Radio Lab; online through such sites as Transom, the Public Radio Exchange, Hearing Voices, and Soundprint; and through a growing collection of podcasts. Reality Radio celebrates today's best audio documentary work by bringing together some of the most influential and innovative practitioners from the United States, Canada, the United Kingdom, and Australia. In these nineteen essays, documentary artists tell--and demonstrate, through stories and transcripts--how they make radio the way they do, and why. Whether the contributors to the volume call themselves journalists, storytellers, even audio artists--and although their essays are just as diverse in content and approach--all use sound to tell true stories, artfully.
