Patent ID: 7170924

Claim:
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 for determining combiner weights applied in the combiner, comprising: receiving a frame comprising samples of a first type of symbols from a plurality 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 the adaptive algorithm is a recursive least squares algorithm, and wherein the determining includes iteratively calculating a combiner weight as a function of at least one previous combiner weight, and a received signal comprising the first type of symbols, and further wherein the 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.
