ABSTRACT:
A communication device for receiving a signal in the form of a series of bursts, each burst being in one of a plurality of different available transmission modes, the communication device comprising: a receiver unit coupled to a single antenna operable to receive bursts in first and second polarizations, the receiver unit preferentially receiving signals in a selected polarization; a selection unit for selecting for each received burst in which polarization the receiver unit is to preferentially receive signals; and a signal analysis unit for analyzing each received burst to determine whether it meets a predetermined reception quality criterion; wherein the signal analysis unit is arranged to control the selection unit to: if a burst is to be received with a certain transmission mode and the last burst received with that transmission mode was received above the reception quality criterion, preferentially receive the burst in the same polarization in which the last burst was received; and if a burst is to be received with a certain transmission mode and the last burst received with that transmission mode was received below the reception quality criterion, preferentially receive the burst in a different polarization from that in which the last burst was received.
