  • Apparatus and method for DC offset calibration in system
    Patent number: 8340600
    Abstract: An apparatus and method for DC offset calibration in a system are provided. The method of a DC offset calibrator for calibrating a DC offset on a system transmission path includes variably setting offset values to be applied to transmit signals of a system, transmitting the variably set offset values to the system, measuring a DC component output value at an antenna end of the system for the transmit signals to which the variably set offset values are applied, and, when the measured DC component output value has a value allowable in the system, determining the variably set offset values as final offset values to be applied to the system.
