FIELD: radio engineering, communication.SUBSTANCE: with respect to the band signal which was initially received, phase noise is eliminated from the carrier phase signal by applying a filter property with a default value. A transmission side phase noise property is extracted from a ratio frame demodulated from the carrier signal, and added to a predetermined receiving side phase noise property so as to calculate the full phase noise property. The full phase noise property and the threshold value are compared to select an optimum filter property. With respect to a subsequent band signal, the selected filter property is applied to eliminate a noise component from the carrier phase signal.EFFECT: improved stabilisation of carrier synchronisation.10 cl, 4 dwg |
