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 total number of filter coefficients; - setting the rest of the filter coefficients to one, wherein the rest of the filter coefficients are the total number of filter coefficients minus the retrieved filter coefficients; - normalising the retrieved filter coefficients, with regards to the Notch depth and noise floor; transforming the filter coefficients such that the Notch position ends up at the one or more frequencies to be filtered out, wherein the action of transforming the filter coefficients to achieve the desired Notch position further comprises: - determining a shift index as the number of harmonics, wherein the number of harmonics are the number of filter periods that are required to cover the desired position; - mirroring the filter coefficients around the centre coefficient if the difference between the desired position and the periodicity of the filter times the number of harmonics is negative, wherein the periodicity of the filter is given as the sampling rate divided by the number of filter coefficients; - circularly shifting the filter coefficients according to the shift index, wherein when the number of harmonics is negative the shift is to the left, whereas when the number of harmonics is positive the shift is to the right. - 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; - setting the rest of the filter coefficients to one, wherein the rest of the filter coefficients are the total number of filter coefficients minus the retrieved filter coefficients; - normalising the retrieved filter coefficients, with regards to the Notch depth and noise floor; transforming the filter coefficients such that the Notch position ends up at the one or more frequencies to be filtered out, wherein the action of transforming the filter coefficients to achieve the desired Notch position further comprises: - determining a shift index as the number of harmonics, wherein the number of harmonics are the number of filter periods that are required to cover the desired position; - mirroring the filter coefficients around the centre coefficient if the difference between the desired position and the periodicity of the filter times the number of harmonics is negative, wherein the periodicity of the filter is given as the sampling rate divided by the number of filter coefficients; - circularly shifting the filter coefficients according to the shift index, wherein when the number of harmonics is negative the shift is to the left, whereas when the number of harmonics is positive the shift is to the right. - determining a shift index as the number of harmonics, wherein the number of harmonics are the number of filter periods that are required to cover the desired position; - mirroring the filter coefficients around the centre coefficient if the difference between the desired position and the periodicity of the filter times the number of harmonics is negative, wherein the periodicity of the filter is given as the sampling rate divided by the number of filter coefficients; - circularly shifting the filter coefficients according to the shift index, wherein when the number of harmonics is negative the shift is to the left, whereas when the number of harmonics is positive the shift is to the right.
