<P>PROBLEM TO BE SOLVED: To provide an OFDM signal transmitter in which compound third distortion is reduced without lowering transmission power of pilot subcarrier. <P>SOLUTION: First subcarrier signal and second subcarrier signal are generated by inputting first and second data subcarriers generated from a transmission signal 102 to a pilot subcarrier inserting section 106, and inserting first and second pilot subcarriers having different polarity, respectively, between the first data subcarriers, and between the second data subcarriers. First and second OFDM signals a and b are then generated from the first and second subcarrier signals and transmitted from different transmission antennas. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
