Abstract (en)
[origin: WO2020120333A1] The invention relates to a method for interference suppression, wherein: a. a time signal (10) is provided, b. an interference range (16) of the time signal (10) is determined, c. a modified time signal (18) is provided by suppressing the interference range (16) of the time signal (18), d. a spectrum (20) of the modified time signal (18) is determined and a suppression spectrum (28) of the suppressed interference range (16) is determined, e. a real frequency component (30) of the spectrum (20) is determined, f. a modified suppression spectrum (34) is determined from a characteristic variable of the real frequency component (30) of the suppression spectrum (28), g. the modified suppression spectrum (34) is subtracted from the spectrum (20) to provide a corrected spectrum (36). The invention also relates to two methods for signal restoration on the basis of the method for interference suppression.
