Abstract
The invention relates to a radio system and a transceiver method. The method comprises the steps of transmitting a signal of at least one type by a transceiver of the first type; receiving a signal by a transceiver of the second type with at least two differently polarized antennas; performing measurements of the received signal to determine its polarization by using the transceiver of the second type; determining the polarization of the transceiver of the first type; adjusting the signal transmitted by the transceiver of the second type in such a way that the polarization of the signal is matched with the polarization used by the transceiver of the first type; transmitting at least two orthogonally polarized, polarization-matched signals by the transceiver of the second type; and receiving the polarization-matched signals by the transceiver of the first type by using at least two antennas of different polarizations.
