Abstract
Systems and methods for handling cancellation of a Passive Intermodulation (PIM) signal are provided. The network device has access to and controls one or more transmitters and one or more receivers. The network device applies a determined PIM model to a transmitted signal from each transmitter of the network device, to obtain a modelled signal. The PIM model comprises a forward path model for each transmitter to the PIM source, a common non-linear model of the PIM signal from the PIM source being applied to a combined signal comprising the signals from each transmitter modelled by the forward path model, and a linear reflective path model from the PIM source to each of the receivers of the network device for a received PIM signal. The network device further subtracts the modelled signal from a received signal on each of the receivers of the network device.
