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 weighted and combined to provide the processed signal; and a generation circuit for computing a weight vector. The weight vector has a number of weights greater than the plurality of received signals and is computed as a least-squares problem solution.
