ABSTRACT:
The method is for receiving an OFDM signal according to which, during a frequency translation phase, there is introduced a phase and gain imbalance between the phase and quadrature components thereof, and a frequency offset relative to a main carrier of the OFDM signal. The method involves a compensation of the effects of the imbalance even in the presence of the frequency offset and provides a reference signal indicative of the effect of the imbalance and according to which a process is carried out to reduce the effect of the imbalance itself.
