Volume   Number 6 

 In this letter, we propose a new architecture for simultaneous wireless information and power transfer (SWIPT) which utilizes multi-sine waveforms for energy transfer and their distinct peak-to-average-power-ratios (PAPR) for information transmission. A new form of SWIPT proposed is based on an innovative idea of conveying information using the different levels of PAPR which can be measured at the output of the rectifier for energy harvesting, enabling a low-energy combined receiver. The latter is very crucial for batteryless operation of low-energy wireless devices relying much on the harvested energy. We demonstrate how the proposed idea works in terms of the information decoding via distinct PAPR, as well as the rateenergy tradeoff for a varying number of multiple tones.
