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 where the received signals are multiplied by weights and combined; and a weight generation circuit for generating the weights; wherein the received signals are sampled at a multiple of a symbol rate, different weights for each set of samples at a symbol rate are generated and the weights are selected to optimize performance.
