Abstract (en)

[origin: WO2006018035A1] An apparatus for reducing a phase drift in a spectrum of a time-domain signal comprises a transformer (101) for time-frequency transforming the time-domain signal into a transformed signal in the frequency domain, the transformed signal representing a spectrum of the time domain signal, a detector (109) for detecting the phase drift, the detector (109) being further configured for generating a control signal indicating the phase drift, wherein the transformer (101) is further configured, in response to the control signal, for pre-processing the time-domain signal before time-frequency transforming or for post-processing the transformed signal after time-frequency transforming the time-domain signal in order to introduce a correction phase drift to the transformed signal for phase drift reduction, the correction phase drift at least partly compensating the phase drift.
