Radio communication system, device and method

Abstract

Disclosed is a radio communication system for performing data communication by a backscatter system using absorption and reflection of a received radio wave, wherein a data reading device transmits an unmodulated carrier of frequency fO; a data transmitting device subjects transmission data to primary modulation with a center frequency fS, and subjects a signal resulting from the primary modulation (12) to secondary modulation (13) by multiplying the signal resulting from the primary modulation by an input of the unmodulated carrier of the backscatter system so as to generate a reflected modulated wave in which one of frequencies fO + fS and fO - fS is suppressed; and the data reading device receives a reflected wave signal in which one of the frequencies fO + fS and fO - fS is suppressed from the data transmitting device.
