Simultaneous wireless information and power transfer (SWIPT) has emerged as aviable technique to energize and connect low-power autonomous devices andenable future Internet of Things (IoT) A major challenge of SWIPT is the energy consumption of the receiver of such low-powered devices . New method transmits high amplitude pulses to increase thePeak-to-Average Power Ratio (PAPR) of the transmit signal and exploits the EH’s nonlinearity so as to boost the harvested DC power . Simultaneously, the information can be decoded from the rectifier signal by simply finding theposition of the pulse in a certain symbol duration . Such architecture eliminates the need for energy-consuming RF components such as local oscillators and mixers such as Local Oscillators and other mixers . The proposed PPM scheme was compared and contrasted to conventional signals. Theoretical, numerical, and experimental results highlight the significant benefits of the proposed PIM scheme to enhance the power transfer performance and operate information decoding withlow-power consumption. We have analyzed both the information and the new PPM system testbed in an indoor environment, we have established a SWIPt system test bed in an outdoor environment by prototyping a SWipT system
