A mobile device receives downlink transmissions comprising replicas of an original downlink transmitted signal over corresponding fingers of a RAKE receiver comprising arithmetic units. The RAKE receiver computes a cell normalization factor for each of active cells and neighbor cells associated with the RAKE receiver. The RAKE receiver uses the same arithmetic units comprising one adder, one multiplier, one divider and/or one square root unit to compute cell normalization factors. The received downlink transmitted signal is processed using the computed cell normalization factors. The RAKE receiver determines signal power from each of other cells, separately, to compute cell normalization factors to normalize fingers of the RAKE receiver. Interference over the normalized fingers are cancelled and used to process the received downlink transmitted signal, which are combined and Turbo decoded. Phase correction is performed over interference cancelled fingers for active cells, but need not be performed for neighbor cells. |
