Summary:Embodiments herein describe adapting a PIM model to compensate for changing PIM interference. A PIM model can include circuitry that generates a PIM compensation value that compensates for (i.e., mitigates or subtracts) PIM interference caused by transmitting two or more transmitter (TX) carriers in the same path. The disclosed adaptive scheme generates updated coefficients for the PIM model which are calculated after the RX signal has been removed from the RX channel. In this manner, as the PIM interference changes due to environmental conditions (e.g., temperature at the base station), the adaptive scheme can update the PIM model to generate a PIM compensation value that cancels the PIM interference.
