System and method for adjusting combiner weights using an adaptive algorithm in a wireless communications system
Abstract
In a wireless communication system having a plurality of receive antennas, each coupled to a rake receiver, and a combiner for combining signals from rake fingers of each rake receiver, a method, apparatus and computer-readable medium are described for determining combiner weights applied in the combiner, comprising receiving a frame comprising samples of a first type of symbols from a pluralilty of rake receiver outputs and samples of a second type of symbols from the plurality of rake receiver outputs; determining combiner weights for combining the plurality of rake receiver outputs using the samples of the first type of symbols using an adaptive algorithm, wherein each combiner weight is a function of a gain factor determining an amount of past iterative information maintained by the algorithm; and processing the samples of the second type of symbols using the combiner weights.
