Apparatus and method for I/Q mismatch calibration |
摘要 |
There is provided an apparatus and method for In-phase/Quadrature-phase (I/Q) mismatch calibration. The apparatus includes: a symmetrical point extracting part receiving continuous wave signals and extracting an I/Q channel average locus of the continuous wave signals; an error extracting part extracting a degree of distortion of the continuous wave signals from the extracted I/Q channel average locus; and a calibrating part calibrating a mismatch between I-channel signals and Q-channel signals of the continuous wave signals using the degree of distortion of the continuous wave signals. |
