Abstract
The present invention provides a calibrating method of an array antenna transceiver for performing multicarrier transmission capable of minimizing the increase of a transceiver size and a signal processing load and keeping a certain calibration accuracy. A method of calibrating a transmission route using an array antenna transceiver for performing broadband transmission by a multicarrier includes grouping all subcarriers into a plurality of subcarrier groups and calibrating a transmission route for each group.
