We propose a multi-tone amplitude modulation (MAM) scheme and its receiver architecture for simultaneous wireless information and power transfer (SWIPT). The MAM symbol consists of two-dimensional signaling of the amplitude component and the subcarrier-number component. The two components are decoded through the current intensity of rectifier output and peak to average power ratio (PAPR) value, respectively. Harvested energy and symbol error rate (SER) of proposed scheme are analyzed and evaluated for various bit assignments of two components. The simulation results show that proposed scheme achieves improved SER performance while achieving high energy harvesting.
