Low-Power Receiver Architecture for 5G and IoT-Oriented Wireless Information and Power Transfer Applications
A low-power receiver architecture is introduced and studied for simultaneous wireless information and power transfer (WIPT) applications. The concept of WIPT is developed for energy-constrained wireless nodes without compromising the information receiver performance characteristics and the use of digital modulation techniques for 5G-oriented internet-of-things (IOT). With a diplexer-based six-port receiver, it is found that dedicated wireless power transfer is realizable along with simultaneous wireless information transfer. A multiport power recycling method is also deployed which exploits the unwanted harmonic signals generated by power detectors and signal interferers.
