  • Apparatus and method for calibrating and compensating for distortion of an output signal in a smart antenna
    Patent number: 7292877
    Abstract: Disclosed is an apparatus and method for calibrating and compensating for distortion of an output signal to an antenna in a mobile communication system with a smart antenna array. A calibration signal generator generates an extended Walsh code by extending a Walsh code used in the mobile communication system, and generates a calibration signal in synchronism with a Walsh code synchronization signal of the mobile communication system. A mobile communication signal generator generates a traffic signal for forming a beam pattern to a position of a mobile terminal in communication. A multiplier multiplies an error compensation value by an output signal of the mobile communication signal generator. An adder adds an output of the multiplier to an output signal of the calibration signal generator.
