Abstract
A methods for performing a cell search in multiple antenna wireless systems using a plurality of spatial filters is disclosed, and includes applying a plurality of spatial filters to a plurality of received signal streams to generate a plurality of filtered signal streams. The plurality of received signal streams correspond to signals received at a plurality of receive antennas from a plurality of signal sources (e.g., neighboring cells). In an aspect, the plurality of spatial filters may be predefined spatial filters and may be weighted using a set of predefined filter weights. In an additional or alternative aspect, the plurality of spatial filters may be adaptive spatial filters and may be weighted using a set of dynamically determined filter weights. The method includes detecting physical network identities based on the plurality of filtered signal streams.
