Abstract
A radio communication receiver and a method performed by the radio communication receiver for configuring a Notch filter of the radio communication receiver. The method comprises retrieving stored and previously determined filter coefficients from a set of filter coefficients, where the retrieved filter coefficients constitute a fraction of the total number of filter coefficients; and setting the rest of the filter coefficients to one. The method further comprises normalising the retrieved filter coefficients; and transforming the filter coefficients such that the Notch position ends up at the one or more frequencies to be filtered out.
Claims30
A method performed by a radio communication receiver for configuring a Notch filter of the radio communication receiver for filtering out one or more frequencies, the method comprising:
- retrieving stored and previously determined filter coefficients from a set of filter coefficients, where the retrieved filter coefficients constitute a fraction of the set of filter coefficients;
- setting the rest of the filter coefficients of the set of filter coefficients to one;
- normalising the retrieved filter coefficients;
- transforming the filter coefficients such that a Notch position filters one or more frequencies.
