Signal combiner for a radio communication base station arrangement

摘要

This invention relates to radio communication systems and provides a signal combiner for a radio communications system having a number of receiving antennas. The signal combiner receives signals from all receiving antennas and provides a combination technique with performance close to optimal (maximal ratio) combiners but without the complexity. The invention provides a base station (10) arrangement which only processes the outputs from antennas (12) which contribute positively to the overall system carrier-to-noise ratio.
