SLINR SWIPT TRANSMITTING/RECEIVING APPARATUS AND METHOD IN SWIPT SYSTEM USING PRECODING SCHEME BASED ON SLINR

摘要

The present invention relates to a transmitting/receiving apparatus in a simultaneous wireless information and power transfer (SWIPT) system using a precoding scheme based on a signal to leakage interference plus noise ratio (SLINR), and a method thereof. The transmitting apparatus in an SWIPT system comprises: a channel information checking unit for dividing an energy user receiving wireless power and a data user receiving wireless data, and checking channel information of a downlink channel for each of the energy user and the data user; a precoder generating unit for increasing the amount of leakage signals which is an interference signal facing the energy user based on the channel information, and generating a precoder value to decrease the amount of interference signals facing the data user; and a transmitting unit for reflecting the generated precoder value on transmitting signals for each of the energy user and the data user to transmit the transmitting signals.
