Method of compensating for interference in a signal generated by discrete multitone modulation, and circuit configuration for carrying out the method.

A circuit configuration for compensating for interference in a signal generated by discrete multitone modulation, the signal generated by discrete multitone modulation having a multiplicity of carrier frequencies in the frequency domain, and each carrier frequency having a signal vector, comprising:

• a first decision circuit receiving a reference signal vector, said first decision circuit mapping the reference signal vector into a value-discrete reference signal vector;
• a subtractor circuit connected to said first decision circuit for forming an error signal vector by subtracting the reference signal vector and the value-discrete reference signal vector from one another;
• a multiplicity of adders receiving the error signal vector and adding the error signal vector to each of the remaining signal vectors, except for the reference signal vector;
• and
• multiplier circuits connected upstream of each of said adders in a signal flow direction, said multiplier circuits multiplying the error signal vector by adjustable coefficients.

A method of compensating for interference in a signal generated by discrete multitone modulation, wherein the signal generated by discrete multitone modulation has a multiplicity of carrier frequencies each having a signal vector, which comprises the following method steps:

• defining a signal vector of a multiplicity of signal vectors in a signal generated by discrete multitone modulation as a reference signal vector;
• generating an error signal vector from the reference signal vector;
• calculating interference with the remaining signal vectors of the multiplicity of signal vectors in approximation from the error signal vector;
• and
• subtracting the calculated interference from the respective signal vector of the multiplicity of signal vectors for interference compensation.
