ABSTRACT:
For processing a sequence of samples of a signal, it is assumed that the signal comprises a carrier that is modulated by a code composed of a sequence of chips. A method of wiping-off an influence by the carrier on the sequence of samples and downsampling the sequence of samples (step105; step205; step301) is shown, as well as utilizing the downsampled sequence of samples as a new sequence of samples for further processing (step108; step209; step302). Also shown are a corresponding processing component72, a corresponding electronic device71, a corresponding system, a corresponding software program code and a corresponding software program product.
