Abstract

For estimating a frequency offset in a communication receiver, the invention proposes to transform a sequence of complex-valued samples from a first receiver stage into a sequence of frequency bins as a frequency domain representation, to scan the frequency bins to find those frequencies where the frequency domain representation is flat, and to modify a down conversion stage of the receiver depending on the found frequencies.
