Abstract
A communication device includes: a reception element for receiving a radio signal modulated in a first modulation scheme or a second modulation scheme; a first demodulation element for demodulating the received radio signal in a first demodulation scheme corresponding to the first modulation scheme; a second demodulation element for demodulating the received radio signal in a second demodulation scheme corresponding to the second modulation scheme; and a modulation scheme detection section for detecting a modulation scheme of the received radio signal. The received radio signal includes modulation scheme determination information. The modulation scheme detection section detects the modulation scheme of the received radio signal based on a result of demodulation of the modulation scheme determination information performed by the first demodulation element and a result of demodulation of the modulation scheme determination information performed by the second demodulation element.
