The invention relates to a method for processing of a signal (s), wherein desired data (d(f(N))) are received via a desired channel (N) of a plurality of frequency channels (N−2, N−1, N, N+1, N+2) and unwanted data (d(f(N−2)), d(f(N−1)), d(f(N+1)), d(f(N+2))) can be received on a neighboring channel (N−2, N−1, N+1, N+2) and wherein the signal (s) is sampled with a sampling frequency (fa) to avoid aliasing of the desired channel (N) in order to create digital data (do), wherein the sampling frequency (fa=2f(N−1, N, N+1)) is set high enough for aliasing-free sampling of the desired channel (N) and at least one of the neighboring channels (N−1, N+1).
