Claim 0:
1. An apparatus for determining an interference in a transmission medium during a transmission of a data input signal, comprising:
a transform module configured to transform the data input signal from a time domain to a frequency domain comprising a plurality of frequency channels to acquire a frequency-domain data signal comprising a plurality of spectral coefficients, wherein each spectral coefficient of the plurality of spectral coefficients is assigned to one of the plurality of frequency channels, and
an analysis module configured to determine the interference by determining one or more spectral interference coefficients, wherein each of the one or more spectral interference coefficients is assigned to one of the plurality of frequency channels,
wherein the analysis module configured to determine each of the one or more spectral interference coefficients depending on the plurality of spectral coefficients and depending on a transfer function, wherein the transfer function is configured to receive two or more argument values, wherein each of the two or more argument values indicates one of the plurality of frequency channels, and wherein the transfer function is configured to return a return value depending on the two or more argument values.
