The present invention concerns a method for determining a power of at least one crosspolar interferer in a frame received by a receiver comprising at least a first and a second receive antennas detecting a first and a second polarization, the frame being transmitted from a satellite transmitter comprising at least a first and a second transmit antennas, the first transmit antenna being used for transferring signal representative of the frames to the receiver on the first polarization, the second transmit antenna being used for transferring signal to another receiver using the same frequency and the second polarization. The method comprises the steps of: - obtaining the antenna gains between the satellite transmitter and the receiver, - estimating a value of the atmospheric attenuation between the satellite transmitter and the receiver, a crosspolar attenuation, the channels between the first and second transmit antennas and the receiver, - estimating the power of the at least one interferer from the obtained antennas gains and estimations. |
