Abstract: Interference (I3) in a waveform received at a device in a wireless network is processed, the processing, for example, being used to detect and/or reduce the interference. The interference comprises non-linear products of at least a first signal. On the basis of at least the first signal, a plurality of interference product streams are generated, each stream comprising a stream of time samples of a simulated non-linear product of at least the first signal. At least two of the plurality of interference product streams are processed to reduce a degree of correlation between said at least two interference product streams thereby producing at least two processed interference product streams, which are correlated with the received waveform to produce a plurality of respective correlation values. The interference is processed in dependence on the plurality of respective correlation values.

Abstract: Interference is processed in a waveform received at a device in a wireless network, the received interference comprising non-linear products of at least a first signal (C1) at a first carrier frequency and a second signal (C2) at a second carrier frequency. A complex composite baseband signal is generated comprising at least the first and second signal at baseband, occupying a respective first and second frequency range within a composite baseband frequency range and not overlapping in frequency. The complex composite baseband signal is processed by applying at least a first non-linear function (74a) to generate simulated interference comprising at least one simulated non-linear product. The received interference is then processed in dependence on the simulated interference.

Abstract: Interference in a data stream carrying a plurality of uplink signals received in a wireless network is processed, the interference comprising a non-linear product (I3) of at least one downlink signal (C1) of the wireless network. The data stream carrying the plurality of uplink signals and at least a first data stream carrying a plurality of downlink signals is received, and data representing signals received at a first uplink carrier frequency is selected from the data stream carrying the plurality of uplink signals. Data representing signals at at least a first downlink carrier frequency is selected from at least the first data stream carrying the plurality of downlink signals. Interference is detected in the selected data representing signals received at the first uplink carrier frequency by correlation with a synthesized product generated from at least data representing signals at the first downlink carrier frequency.
