Abstract:
Methods and apparatus are disclosed for processing interference due to passive non-linear products of transmitted signals in a wireless network, and more specifically, but not exclusively, to reduction of interference caused to a receiver due to passive intermodulation (PIM) products generated from at least a first Multiple Input Multiple Output (MIMO) signal comprising first and second MIMO component streams at a first carrier frequency. In other scenarios, there may be two or more carrier frequencies combining to cause PIM, and each carrier frequency may have two or more MIMO component streams.

Claim (Index 13):
Apparatus comprising one or more processors, the apparatus being configured to process interference in a waveform received at the input of a receiver in a wireless network, the interference comprising PIM (Passive Intermodulation) products generated from at least a first MIMO (Multiple Input Multiple Output) signal comprising at least a first and second MIMO component stream at a first carrier frequency, the one or more processors being configured to cause the apparatus to:\n generate a first simulated PIM component to simulate a first component of the PIM products by applying a first nonlinear PIM simulation function to a linear combination of a plurality of baseband streams, the plurality of baseband streams comprising at least a first baseband stream representing the first MIMO component stream, a second baseband stream representing the second MIMO component stream, wherein the first baseband stream is combined with the second baseband stream in a first amplitude and phase relationship; generate a second simulated PIM component to simulate a second component of the PIM products by applying a second nonlinear PIM simulation function to a linear combination of said plurality of baseband streams, wherein the first baseband stream is combined with the second baseband stream in a second amplitude and phase relationship, different from the first amplitude and phase relationship; and reduce the interference in the received waveform by subtraction of the first and second simulated PIM components.
