Abstract: An operating method of a wireless communication device, the method including generating an IQ compensation value by performing IQ mismatch compensation on a first input signal using a linearity calibration model, the linearity calibration model being based on a neural network, generating a pre-distortion value by performing pre-distortion on the first input signal using the linearity calibration model, generating a first calibration signal based on the IQ compensation value and the pre-distortion value, generating a calibrated first output signal by amplifying the first calibration signal based on an amplification coefficient, and training the linearity calibration model based on the first input signal and the calibrated first output signal.
