Abstract
Standardized wireless communication systems based on radio frequency (RF) radiation are one of the important technologies in the modern societies. The emergence of low‐power autonomous wireless devices, such as ubiquitous sensing through wireless sensor networks (WSN) or an Internet‐of‐Things (IoT), has made the powering of such devices another challenge for the next generation 5G mobile networks. This chapter provides an overview of a wireless power transfer (WPT) architecture and the latest advances in the field of signal design for WPT and sequence wireless information power transfer (SWIPT). In order to demonstrate the feasibility of the proposed signal and system designs for WPT, prototyping and experimentation are required. Utilizing the WPT waveform designs shows that the rectifier nonlinearity has a significant impact on the performance of a SWIPT system.
