Apparatus comprises: a first correlator configured to correlate a first signal component with a first code to provide a first output, said first signal component having a carrier frequency and data; a second correlator configured to correlate a second signal component with a second code to provide a second output, said second signal component having the same carrier frequency as the first signal component and the same data as the first signal component, said data on the second signal component being delayed with respect to the data on the first signal component; and a processor configured to process the first and second outputs, said data on said first output being aligned with the second output to provide frequency information about said carrier. |
