Abstract
A radio receiver device is provided. The radio receiver device is arranged to receive a radio signal comprising a symbol sequence corresponding to a training sequence; to determine a first autocorrelation of said symbol sequence using a first autocorrelation latency; to determine a second autocorrelation of said symbol sequence using a second autocorrelation latency that is longer than the first autocorrelation latency; and to combine said first and second autocorrelations to determine an estimate of carrier frequency offset between the radio signal and the radio receiver device.
