Patent ID: 8693954

Claim:
A method for reducing the influence of an interfering signal (S i ) on a wanted signal (S w ) in a first frequency channel (n) received by a receiver when the interfering signal (S i ) occurs in a second frequency channel (n+1) near to the first channel (n), which method in an access point comprises the steps of: assuming a model (S T ) of a transmitter causing the interfering signal (S i ), obtaining in the first channel (n) a measure of the wanted signal (S w ) and a measure of a nonlinear part of the interfering signal (S i ), and in the second channel (n+1) a measure of a linear part of the interfering signal (S i ), solving the model for said transmitter by using the measured linear and nonlinear part, obtaining the interfering signal (S i ) influencing the first channel (n) by using the solved model, and subtracting the obtained interfering signal (S i ) from the wanted signal (S w ) received by the receiver, wherein said receiver comprises a first receiving branch and a second receiving branch for supporting space diversity, the method further comprising the steps of: obtaining said wanted signal (S w ) and said nonlinear part of the interfering signal (S i ) by measuring in the second branch, and obtaining said linear part of the interfering signal (S i ) by measuring in the first branch.
