Abstract
Certain aspects of a method and system for delay matching in a rake receiver for WCDMA closed loop modes are disclosed. Aspects of one method may include selecting a set of channel estimates from a plurality of channel estimates generated for a delay matched branch and/or a non-delay matched branch in a rake receiver. A plurality of weight factors may be generated based on the selected set of channel estimates. In the delay matched branch of the rake receiver, the application of the generated plurality of weight factors may be delayed by a particular time period. A delay associated with a control channel and/or a data channel may be compensated based on the delayed application of the generated plurality of weight factors.
