<p>The invention, which relates to a method and an arrangement for signal processing in a receiver that can be tuned to different carriers, is based on the object of providing a method and an associated circuit arrangement for signal processing whereby the outlay in the development and production of receivers that support a plurality of standards and the space requirement on the chip arc reduced. According to the invention, the object formulated is achieved according to the method by virtue of the fact that 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, is determined from the digital signal, in that the energy value of the carriers N + 1 and N - 1 determined are compared with a threshold value, in that in the case where the threshold value is exceeded, a frequency shift of the signal by +Δf or -Δf is effected in the second method step prior to the filtering, and in that the frequency shift thus produced is reversed by a frequency shift by -Δf or +Δf in the fourth method step prior to the filtering and the signal is decoded.
