Processing a sequence of samples of a signal using downsampling
First Claim
1. A method for processing a sequence of samples of a signal, said signal comprises a carrier that is modulated by a code composed of a sequence of chips, said method comprising at a receiver:
- a) wiping-off, by said receiver, an influence by said carrier on said sequence of samples and downsampling said sequence of samples, said wiping-off and downsampling comprising combining respective subsequent samples of a predetermined number of said sequence of samples and exploiting regularities in said sequence of samples in said combining, to obtain a sequence of combined values as a downsampled sequence of samples; and
b) utilizing said downsampled sequence of samples as a new sequence of samples for further processing.

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 (step 105; step 205; step 301) is shown, as well as utilizing the downsampled sequence of samples as a new sequence of samples for further processing (step 108; step 209; step 302). Also shown are a corresponding processing component 72, a corresponding electronic device 71, a corresponding system, a corresponding software program code and a corresponding software program product.
