Abstract

Cancelling of intermodulation interference is described. A digital signal sample (x) is received and a power of the received digital signal sample is obtained (). Based on the obtained power, at least one model value is obtained from a model () that models model values of a non-linearity in amplitude and phase of a received signal that passes through passive and active components in the receiver. The model values correspond to a plurality of powers of the received signal. Intermodulation interference is then cancelled by multiplying () the received digital signal sample with the obtained at least one model value, thereby obtaining an output digital signal sample (y) from which intermodulation interference, inflicted by the receiver, is cancelled.
