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 10):
A passive intermodulation distortion (PIMD) products cancellation system, comprising:\n a first upsampler; wherein the first upsampler is configured to upsample an uplink baseband modulated signal; a second upsampler; wherein the second upsampler is configured to upsample a downlink baseband modulated signal; a time aligner; wherein the time aligner is configured to determine an amount of time delay for the upsampled downlink baseband modulated signal; a time delay coupled to the time aligner and the second upsampler; wherein the time delay is configured to delay the upsampled downlink baseband modulated signal by the determined amount of time delay; a third order PIMD product estimator with a third order power series kernel coupled to the time delay; wherein the third order PIMD product estimator with the third order power series kernel is configured to generate an estimated third order PIMD product; a first subtractor; wherein the first subtractor is configured to generate a first filtered signal by subtracting the estimated third order PIMD product from the upsampled uplink baseband modulated signal; a Nth order PIMD product estimator with a Nth order power series kernel coupled to the time delay; wherein the Nth order PIMD product estimator with the Nth order power series kernel is configured to generate an estimated Nth order PIMD product; a nth subtractor coupled to the first subtractor; wherein the nth subtractor is configured to generate a nth filtered signal by subtracting the estimated Nth order PIMD product from a n\u22121th filtered signal; a downsampler; and wherein the downsampler is configured to downsample the nth filtered signal.
