Abstract:
1. A radio relay apparatus that relays communication between a radio transmitting apparatus and a radio receiving apparatus, comprising: a demodulation section that demodulates a signal transmitted from the radio transmitting apparatus to obtain a plurality of bits constituting each symbol of the demodulated signal, the plurality of bits including an amplitude bit that varies when an amplitude of the symbol of the demodulated signal changes and a phase bit that varies when a phase of the symbol of the demodulated signal changes; a decoding section that decodes the amplitude bit among the plurality of bits, to obtain a signal directed only to the radio relay apparatus itself; a modulation section that modulates only the phase bit among the plurality of bits to generate a relay signal directed to the radio receiving apparatus; and a transmitting section that transmits a relay signal only including the phase bit modulated by the modulation section.
