Systems and methods for cancellation of passive intermodulation (pim) for a wireless network receiver

Abstract

There is provided a passive intermodulation (PIM) mitigation module for mitigating PIM within a receiver of a wireless network, the PIM mitigation module comprising: at least one processor executing a code for: receiving transmit signals transmitted by at least one transmission source, receiving received signals received by at least one reception source, computing a plurality of synthetic PIM signals from the transmit signals, wherein each of the plurality of synthetic PIM signals is a respective combination of a plurality of frequency components of the transmit signals, computing a plurality of mitigation weights for mitigating the plurality of synthetic PIM signals, and performing a PIM mitigation process on the received signal with the plurality of mitigation weights to generate clean signals to provide to the receiver.
