Abstract:
1. An apparatus, comprising: an interference cancellation functional block that de-spreads, slices, re-spreads, and convolves a signal, that includes inter-code interference, using a selected plurality of interference cancellation filter taps, that is selected to notch out ingress or narrowband interference within the re-spread signal, thereby generating a convolved signal; a delay element that receives the signal and delays the signal for a period of time substantially matching a time the signal is processed within the interference cancellation functional block; and wherein: the convolved signal is subtracted from a delayed output signal that is provided from the delay element thereby generating a cleaned signal; an output de-spread functional block that generates a plurality of output soft decisions from the cleaned signal; and an output slicer that generates a plurality of output hard decisions using the plurality of output soft decisions.
