摘要
A method processes defects in a radio frequency transmission subsystem due to elements therein. The defects may include mismatch between two channels in phase quadrature in the transmission subsystem and a transposition signal leaking from a first frequency transposition stage of the transmission subsystem. The method may include calibration processing including estimating compensation parameters representative of the defects. The estimating may include delivering, into the transmission subsystem upstream of the elements creating the defects, a reference signal having a reference frequency, obtaining, downstream of the first transposition stage, of a resultant reference signal, and obtaining, from the resultant reference signal, of an approximate value for each compensation parameter. The method also may include compensating for the defects by injecting the approximate values into the transmission subsystem.
