Abstract
A non-contact wireless communication apparatus that includes: an antenna section configured to receive a carrier wave; an envelope-curve shaping section configured to shape a falling waveform of an envelope curve of the carrier wave into a gradual falling waveform; and a demodulation section configured to extract the envelope curve shaped by the envelope-curve shaping section and perform envelope-curve detection by binarizing the envelope curve with a predetermined threshold value.
