The invention is directed to a method for reducing the influence of an interfering signal Si on a wanted signal Sw in a first frequency channel n received by a receiver 112a′ when the interfering signal Si occurs in a second frequency channel n+1 near to the first channel n. The method comprises the steps of: assuming a model Sτof a transmitter 120b′ causing the interfering signal Si; obtaining in the first channel n a measure of the wanted signal Sw and a measure of a nonlinear part of the interfering signal Si, and in the second channel n+1 a measure of a linear part of the interfering signal Si; solving the model for said transmitter 120b′ by using the measured linear and nonlinear part; and obtaining the interfering signal Si; influencing the first channel n by using the solved model, and subtracting the obtained interfering signal S1 from the wanted signal Sw received by the receiver 112a′.
