Abstract
A method of performing adaptive mode switching in a transmitter of a dual mode simultaneous wireless information and power transmission (SWIPT) system, incudes receiving received power of a receiver in a channel; comparing the received power with a predetermined threshold value; selecting one of a single tone mode or a multi-tone mode as a single/multi-tone mode based on the comparison result; selecting a modulation index based on the selected single/multi-tone mode and the received power; and transmitting the selected single/multi-tone mode, the selected modulation index, and a duty cycle to the receiver. The duty cycle is determined based on at least one of power consumed for decoding a single tone signal, power consumed for decoding a multi-tone signal, and power harvested during the channel by the receiver.
