Classification: CPC G  H | IPC H

Claim 0:
1. Method for characterizing effects of coupling in a radiofrequency transceiver apparatus comprising at least one transmit path and at least one receive path, said effects of coupling occurring between a transmit path among the said at least one transmit path and a receive path among the said at least one receive path, the method comprising a calculation of coefficients of a correcting filter comprising:
a step of transmitting a known signal over the said transmit path, the known signal being used to characterize effects of coupling in the radiofrequency transceiver apparatus,
a step of receiving a signal over the said receive path, said signal received over the said receive path comprising the known signal transmitted over the said transmit path,
a step of calculating the coefficients of the correcting filter on the basis of the known signal and of the signal received over the said receive path,
the method being characterized in that it further comprises a step, carried out during transmission of a useful signal over the said transmit path, of filtering a signal transmitted over the said transmit path comprising the useful signal by means of said correcting filter in order to determine a transmitted signal received by coupling effect over the said receive path, referred to as an equivalent coupled signal.
