Zusammenfassung:	A method for reducing a distortion component within a baseband receive signal is provided. The baseband receive signal is derived from a radio frequency signal and the distortion component is related to an undesired signal component of the radio frequency signal. The method includes generating a first local oscillator signal having a frequency related to a frequency of the undesired signal component. Further the method includes generating an auxiliary baseband signal using the radio frequency signal and the first local oscillator signal. The method further includes generating a second local oscillator signal having a frequency related to a frequency of a desired signal component of the radio frequency signal. Further the method includes generating the baseband receive signal using the radio frequency signal and the second local oscillator signal. The method includes modifying the baseband receive signal based on the auxiliary baseband signal.
