PURPOSE: An array antenna transceiver for correcting phase and amplitude characteristics between antennas and a method for correcting a transmission route used therefor are provided to reduce the size of the array antenna transceiver by grouping subcarriers having similar frequency characteristics as well as same transmission routes. CONSTITUTION: An array antenna transceiver includes a device for grouping all subcarriers into a plurality of subcarrier groups and correcting transmission routes of the groups. The device includes a plurality of correction signal demodulators(109-1 to 109-L) for demodulating a transmission route number and a subcarrier number, a demodulation result processor(110) for outputting the transmission route number, the subcarrier number, and a normalized demodulation symbol point, a demodulation symbol area determination unit(112) for receiving the transmission route number, the subcarrier number, and the normalized demodulation symbol point. A correction subcarrier selector(113) for selecting one transmission route number and one subcarrier number, a correction controller(114) for outputting the transmission route number and the subcarrier number, and a plurality of transmission baseband processors(105-1 to 105-N) for setting correction coefficients of all subcarriers in all transmission routes. |
