Abstract
A receiver is a Digital Video Broadcasting-Terrestrial/Handheld (DVB-T/H) receiver. The DVB-T/H receiver comprises a fast fourier transform (FFT) operative on a signal for providing an FFT output signal comprising a number of samples; a spectrum shifter for reordering the samples in the FFT output signal to provide a spectrum shifted signal; and a phase corrector for estimating a phase error from the FFT output signal and for correcting a phase of the spectrum shifted signal in accordance with the estimated phase error.
