Patent ID: 7340281

Claim:
A receiver comprising: an antenna array comprising a plurality of antennas configured to receive signals; a beam former configured to generate a predetermined pattern of a plurality of directional beams, the plurality of beams being grouped into at least two beam sets, the beam sets being offset with respect to each other; said beam former including a control unit configured to periodically switch a beam set for receiving the signals among at least two beam sets in turn while receiving the signals in order to compensate for a signal quality decrease in a cross over point between two adjacent directional beams in a beam set by averaging a signal quality of the received signals over said switched beam sets; a beam selector configured to select a beam from the switched beam set among the generated beams; and, a processor configured to determine estimated data symbols from the received signals via the selected beam, whereby a scalloping loss in a crossover point between two adjacent directional beams is reduced.
