1. A smart antenna communication system comprising:

  • a scheduler for allocating a data signal to a plurality of carriers as data carriers, providing the data signal to a baseband processor, and controlling a calibration processor and a controller to generate a calibration signal to be allocated to non-data carriers to which the data signal is not allocated;

    the calibration processor and the controller for generating the calibration signal on the non-data carriers under the control of the scheduler, and calculating a calibration vector using the calibration signal and a feedback calibration signal, being the calibration signal passed through a transmission path; and

    the baseband processor for calibrating a beamforming weight vector for a data signal with the calibration vector and transmitting the calibrated data signal in the transmission path.
