A method and circuit for signal processing in a receiver that can be tuned to different carriers, the method determining the energy of the adjacent carriers N+1 and N−1, wherein a carrier N contains a signal of interest and the receiver is tuned to it, from the digital signal, in that the energy value of the carriers N+1 and N−1 determined are compared with a threshold value, and in the case where the threshold value is exceeded, a frequency shift of the signal by +&Dgr;f or −&Dgr;f is effected in the second method step prior to the filtering, and the frequency shift thus produced is reversed by a frequency shift by −&Dgr;f or +&Dgr;f prior to the filtering, and the signal is decoded.
