<p>The invention relates to a muiticarrier receiver (301) in a wireless telecommunication network, the muiticarrier receiver comprising; - receiving means (302) for receiving a radio frequency spectrum, the radio frequency spectrum comprising a radio frequency signal (104); - a local oscillator (304) for generating a local -oscillator frequency signal (106;: 110; 202); - a mixer (308) for mixing the radio frequency signal with the local oscillator frequency signal to an intermediate frequency signal (112; 118; 206; 210); - signal processing means (310) for processing the intermediate frequency signal; - a filter (306) for filtering the intermediate frequency spectrum such that only a sub-spectrum (100) of the radio frequency spectrum is processed by the signal processing means; - blocking signal detection means (312) for detecting a frequency of a blocking signal (102; 116; 200) within the sub-spectrum; - local oscillator frequency adjusting means (312) for adjusting the local oscillator frequency such that the frequency of the blocking signal lies outside the sub-spectrum of the radio frequency spectrum.</p> |
