ABSTRACT:
A method is provided for realizing, in a radio transmission system, a carrier synchronization and for cancelling one or more co-channel interfering signals from a received main signal, in which a synchronous down-conversion of the received main signal and of each of the interfering signal is performed to obtain respective intermediate frequency signals; and then a synchronous demodulation of the intermediate frequency signals so obtained is carried out.
