Method for determining calibration parameter of zero intermediate frequency radio receiver, and zero intermediate frequency radio receiver
A method for determining a calibration parameter of a zero intermediate frequency radio receiver, and a zero intermediate frequency radio receiver are provided. The method includes: obtaining a plurality of sub-band training signals, where a sum of the plurality of sub-band training signals is a fullband training signal; determining a sub-band calibration parameter corresponding to each of the plurality of sub-band training signals; determining a fullband calibration signal according to the plurality of sub-band training signals and the sub-band calibration parameter corresponding to each of the plurality of sub-band training signals; and performing coefficient fitting on the fullband training signal and the fullband calibration signal, to determine a fullband calibration parameter. Because sub-band calibration parameters are obtained according to a plurality of different sub-band training signals, aliasing between an image signal and a training signal is reduced. Therefore, a speed and precision of determining a calibration parameter can be improved.
