ABSTRACT:
A device for calculating an overall frequency-offset estimate from a plurality of frequency-offset estimates includes a receiver unit configured to receive a plurality of data streams, a phase shift estimation unit configured to generate a phase shift quantity representative of a phase shift over a number of consecutive data samples in the respective data stream, and a phase shift processing unit coupled to the phase shift estimation unit and configured to calculate a quantity related to the signal-to-noise ratio associated with a data stream on the basis of the respective phase shift quantity. Further, the device includes a frequency-offset estimation unit configured to generate frequency-offset estimates associated with the respective data streams, and a combiner configured to calculate an overall frequency-offset estimate on the basis of the frequency-offset estimates and on the basis of the quantities related to the signal-to-noise ratios.
