Abstract
A frequency error embodied in a series of values is determined by processing each of two or more selected values with another value in the series, each other value being spaced from its respective selected value by a first spacing, to generate processed values that all comprise substantially the same phase component; combining the processed values to generate a combined value that comprises substantially the same phase component as the processed values; repeating the processing and combining with the same selected values but a second spacing, different from the first spacing, to generate a combined value comprising a different phase component from the combined value generated using the first spacing, reflecting the frequency error; and determining the frequency error in dependence on the combined values generated using the first and second spacings.
