Abstract
The present disclosure provides an amplitude offset calibration method. The method includes: obtaining at least two test feedback signals, where the test feedback signals are analog signals obtained by a transmitter in a test mode according to a test signal, at least two test signals in one-to-one correspondence to the at least two test feedback signals are digital signals pre-generated by the transmitter, and amplitudes of the at least two test signals are different; obtaining at least two corresponding baseband signals according to the at least two test feedback signals, where the baseband signals are a digital signal, and the baseband signals are in one-to-one correspondence to the test feedback signals; and determining an amplitude offset value according to the at least two test signals and the at least two baseband signals.
