Abstract
A wireless communication device and a method for IQ calibration are provided. The device includes a transmitting unit for generating a set of RF transmitting signals based on a set of digital baseband signals, each of the set of RF transmitting signals has IQ components; a receiving unit for generating a set of digital feedback signals based on a set of RF receiving signals obtained from the set of RF transmitting signals; a processing unit for obtaining a first set of compensation coefficients for the transmitting unit and a second set of compensation coefficients for the receiving unit based on the set of digital baseband signals and the set of digital feedback signals with an IQ calibration model, the IQ calibration model includes a first high-order term set about a nonlinear error in the transmitting unit and a second high-order term set bout a nonlinear error in the receiving unit.
