<p><P>PROBLEM TO BE SOLVED: To provide a radio communication system capable of excellently reducing the influence of delay waves. <P>SOLUTION: A communication system transmits and receives radio signals by an orthogonal frequency division multiplexing modulation system using a plurality of subcarriers. Transmitters 11 and 12 multiplex a data channel in which a known value is inserted to an unused subcarrier to the radio signals and transmit them. Receivers 12 and 11 receive the radio signals and remove delay wave components from the data channel by interference removal processing utilizing the fact that the known value is inserted to the unused subcarrier. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
