Diversity processing for closed loops may include combining a plurality of received multipath signals to estimate at least one processed diversity signal based on information from at one or more common channels. The common channels may include a dedicated pilot channel transmitted by each diversity antenna. The received multipath signals may originate from diversity transmit antennas at a base station, which may be transmitting information via a closed loop diversity transmission mode. The closed loop diversity transmission mode may be WCDMA/HSDPA closed loop 1 or closed loop 2. Estimations may be made of the closed loop transmit weights used by the base station for transmission of the symbols. Closed loop symbols transmitted by the diversity transmit antennas may then be estimated based on received diversity signals and at least one dedicated pilot channel. At least a portion of the at least one processed diversity signal may be despread.
