Claim:
1. A method of processing interference in a waveform received at a device in a wireless network, the received interference comprising non-linear products generated from at least a first signal at a first carrier frequency and a second signal at a second carrier frequency, the method comprising: generating a complex composite baseband signal comprising at least the first and second signal at baseband, the first signal at baseband occupying a first frequency range within a composite baseband frequency range, and the second signal at baseband occupying a second frequency range within the composite baseband frequency range, the first frequency range not overlapping the second frequency range, by frequency shifting at least one of the first and second signals within the composite baseband frequency range; configuring a difference in frequency between a center of the first frequency range and a center of the second frequency range to be different from a difference in frequency between the first carrier frequency and the second carrier frequency; processing the complex composite baseband signal by applying at least a first non-linear function to generate simulated interference comprising at least one simulated non-linear product; and processing the received interference in dependence on said simulated interference.
