Abstract: Apparatuses (including user equipment (UE) and modem chips for UE), systems, and methods for calculating more accurate Reference Signal Received Power (RSRP) measurements and/or detecting/eliminating ghost cells from a list of (supposed) neighboring cells are described. In one method, the cross-correlations between adjacent Cell-specific Reference Signals (CRSs) are used to calculate the RSRP and to detect any ghost cells in a list of (supposed) neighboring cells. Any detected ghost cell may be deleted from any searches and measurements by the UE, and may also be reported to the network.

Abstract: An interference cancellation (IC) processor, a method, a method of manufacturing a semiconductor device, and a method of constructing an integrated circuit are provided. The IC processor includes a plurality of mono interference cancellation (MIC) filter estimation processors; a combined effective channel calculation processor; a combined filter calculation processor; and a combined filter processor, including a first input connected to the output of the combined filter calculation processor, a second input for receiving a signal for setting a length of the combined filter that is connected to a second input of the IC processor, a third input connected to the input of the MIC-BRC processor, and an output for providing a filtered output of a de-rotated GMSK signal that is connected to a second output of the IC processor that provides a filtered output yi of the de-rotated GMSK signal.
