Apparatus for optimizing received power using adaptive modulation scheme in SWIPT system and method therefor

摘要

An apparatus for optimizing reception power using an adaptive modulation technique according to an embodiment of the present invention includes a communication unit for receiving a signal including information from a slave device or transmitting a signal including power and information to the slave device, and the communication unit When receiving a signal from the slave device through, a distance estimating unit for extracting information for estimating the distance to the slave device from the received signal, and estimating the distance to the slave device using the extracted information, and the And an adaptive processing unit controlling the communication unit to select a modulation method according to the estimated distance, perform modulation according to the selected modulation method, and transmit a signal including power and information to the slave device.
