Abstract
A mobile station () operates in a region where an incumbent operator () is transmitting. The secondary station transmits at a frequency similar to that of the incumbent operator's signal. The incumbent operator transmits using a particular polarization (). To reduce interference, the secondary station selects one of a plurality of antennas of the secondary station which has a low matching polarization with that of the incumbent signal.
