Multicarrier radio communication system

摘要: The present invention makes it possible to transmit data while reducing the influence of fading caused on a transmission path. When communication is transmitted (7) by using plurality subcarriers arranged with predetermined bandwidth, block consisting in rows a time axis direction is used as unit. By implementing both differential modulation process based each phase difference the frequency direction between and differential modulation (21) on each time between subcarriers, a transmission signal symbol superposed a plurality generated output.
