Method and arrangement for antenna diversity in a base station receiver

摘要

This invention relates to radio communication systems and more especially to a base station arrangement comprising means to combine a number of signals input from receiving antennas. This invention is concerned with the combination techniques of spatially diverse systems and in particular seeks to provide 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.
