ABSTRACT:
An apparatus for performance improvement of a digital wireless receiver comprises a processing circuit for processing a plurality of received signals and providing a processed signal, wherein each of the plurality of received signals is multiplied by a corresponding time-varying complex variate to yield one of a plurality of modified signals, and the plurality of modified signals are then weighed and combined to provide the processed signal; and a generation circuit for generating the corresponding time-varying complex variate.
