Abstract
A method for determining a frequency offset from a plurality of signal values is described wherein first correlation coefficients are determined from the signal values and second correlation coefficients are determined from the first correlation coefficients. The second correlation coefficients are linearly combined and the frequency offset is determined as the phase of the linear combination.

A Method for determining a frequency offset from a plurality of signal values, wherein:
- a plurality of first correlation coefficients are determined from the signal values, wherein each first correlation coefficient is determined by determining the correlation between at least two of the signal values;
- a plurality of second correlation coefficients is determined from the plurality of first correlation coefficients, wherein each second correlation coefficient is determined by determining the correlation between at least two of the first correlation coefficients;
- the plurality of second correlation coefficients is linearly combined;
- the frequency offset is determined as the phase of the linear combination.
