Abstract:
A method for diminishing passive intermodulation (PIM) is provided. The method comprises: upsampling an uplink baseband modulated signal; upsampling a downlink baseband modulated signal; determining a time delay for the upsampled downlink baseband modulated signal; time delaying the upsampled downlink baseband modulated signal by the determined time delay; estimating a third order PIM distortion (PIMD) product by filtering the time delayed, upsampled downlink baseband modulated signal with a third order power series kernel; generating a first filtered signal by subtracting the estimated third order PIMD product from the upsampled downlink baseband modulated signal; estimating a Nth order PIMD product by filtering the time delayed, upsampled downlink baseband modulated signal with a Nth order power series kernel; generating a nth filtered signal by subtracting the estimated Nth order PIMD product from the n− 1 th filtered signal; and downsampling the nth filtered signal.

Claim (Index 14):
The PIMD products cancellation system of  claim 10 , wherein the third order PIMD estimator comprises:\n a third order power series kernel having a first input coupled to an output of the time delay; a first frequency shifter coupled to the output of the third order power series kernel; a first bandpass filter coupled to an output of the first frequency shifter and a negative input of the first subtractor; and a first adaptive filter having an input coupled to an output of the first subtractor and an output coupled to a second input of the third order power series kernel; and wherein the Nth order PIMD estimator comprises: a Nth order power series kernel having a first input coupled to an output of the time delay; a nth frequency shifter coupled to the output of the Nth order power series kernel; a nth bandpass filter coupled to an output of the nth frequency shifter and a negative input of the nth subtractor; and a nth adaptive filter having an input coupled to an output of the nth subtractor and an output coupled to a second input of the Nth order power series kernel.
