Radio station constituting a base station for a telecommunication system for wireless telecommunication to/from mobile radio units. The radio station comprises a transmitter unit (8), a receiver unit (7, 9, 11) and a number of antennas (5, 6), and means for diversity reception. The station is expandable with several units (2-4), each one of which comprising an antenna (5, 6) and being arranged at a predetermined distance from one or several antennas in the other units. The antennas forming part of each unit are adapted for reception with space diversity in cooperation with at least one antenna in any of the other units. The antennas within each unit can receive signals with different directions of polarization. The means for diversity reception generates an optimal input signal to the receiver unit by means of an evaluation of input signals from the antennas. The input signals originate from the reception with the antennas which are arranged at different positions in space and also from the reception with different directions of polarization. <IMAGE> |
