Abstract
A communication apparatus includes a generation unit that generates the first I signal and the first Q signal as signals that allow a carrier wave to undergo frequency shift keying with predetermined modulated data and inputs the first I signal and the first Q signal to a quadrature modulation unit. A first demodulation unit and the first decoding unit demodulate and decode first data that undergoes amplitude shift keying and is transmitted from the wireless tag. A second demodulation unit and the second decoding unit demodulate and decode second data that undergoes frequency shift keying from a wireless signal output from the wireless tag. A comparison unit compares the second data and the modulated data to each other. The processor executes, when matching between the second data and the modulated data is confirmed by the comparison unit, data processing on the first data.
