Title: MITIGATING PASSIVE INTERMODULATION INTERFERENCE IN A WIRELESS NETWORK
Abstract:
Interference (I1, I2) is mitigated in a waveform received at the input of a receiver in a wireless network, the interference comprising passive intermodulation PIM products of at least a first signal (C1). A first stream of time samples (5) is generated of a simulated first PFM product of at least the first signal (C1), and a second stream of time samples (6) is generated of the simulated first PIM product. The second stream has a delay with respect to the first stream. A replica (8) is generated of the interference by processing (7) at least the first stream and the second stream, the processing comprising reducing a degree of correlation between the first stream and the second stream, and the replica of the interference is combined with a stream of time samples of the received waveform (40) to reduce the interference in the received waveform.
