Abstract (en)

[origin: US6647076B1] The invention relates to a method for the compensation of interference in a signal generated by discrete multitone modulation. The signal generated by discrete multitone modulation has a multiplicity of carrier frequencies, and each carrier frequency has a signal vector. An error signal vector is generated from a reference signal vector, which is a signal vector from the multiplicity of signal vectors. The error signal vector is added to each of the remaining signal vectors of the multiplicity of signal vectors for the purpose of compensating for interference. Each of the signal vectors of the multiplicity of signal vectors, except for the reference signal vector, is assigned a set of adjustable coefficients by which the error signal vector is multiplied prior to the addition.
