Abstract: Interference comprising an intermodulation product of at least a first signal and a second signal is detected in a wireless network, by generating, on the basis of at least the first signal and the second signal, at least one interference signal comprising a simulated intermodulation product and correlating the at least one interference signal with a waveform received in the wireless system to produce data representing a correlation. The presence of an intermodulation product of at least the first signal and the second signal is detected in the interference in dependence on the data representative of the correlation.

Abstract: A method of processing interference received in a wireless network, the interference comprising a non-linear product of at least one downlink signal of the wireless network, is provided. The method includes intercepting a plurality of optical links, each optical link being between a respective baseband processing unit of a plurality of baseband processing units and a respective radio head of a plurality of radio heads, to provide a plurality of downlink and uplink data streams. The method includes detecting interference in an uplink data stream representing signals received at a first uplink carrier frequency caused by non-linear products of at least a signal at a first downlink carrier frequency represented by a downlink data stream. The method includes generating an indication comprising information relating to an uplink carrier frequency experiencing interference and at least one downlink carrier frequency causing interference.
