Patent ID: 6952562

Claim:
A method for filtering a mobile radiotelephone signal, comprising: filtering a mobile radiotelephone signal received via a mobile radiotelephone channel before processing; and analyzing the received mobile radiotelephone signal for adjacent channel interference, and if adjacent channel interference is determined in the received mobile radiotelephone signal, the signal is selectively filtered before processing to suppress the adjacent channel interference, wherein the received mobile radiotelephone signal comprises sampling values combined into bursts, the mobile radiotelephone signal being analyzed in bursts, and a frequency spectrum of individual bursts in each case is analyzed, in analyzing a burst of the received mobile radiotelephone signal, the adjacent channel interference is detected as energy included at an upper end of the frequency spectrum of the burst and energy included at a lower end of the frequency spectrum of the burst and are defined and compared with one another, and if the adjacent channel interference is detected, the sampling values of the analyzed burst are filtered and output for processing.
