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 8):
The method of  claim 7 , wherein adjusting at least one weight of the third order power series kernel based upon adaptively filtering the first filtered signal comprises adjusting at least one weight of a third order truncated Volterra series kernel based upon adaptively filtering the first filtered signal;\n wherein filtering the time delayed, upsampled downlink baseband modulated signal with the third order power series kernel comprises filtering the time delayed, upsampled downlink baseband modulated signal with the third order truncated Volterra series kernel; wherein adjusting at least one weight of the Nth order power series kernel based upon adaptively filtering the nth filtered signal comprises adjusting at least one weight of the Nth order truncated Volterra series kernel based upon adaptively filtering the nth filtered signal; and filtering the time delayed, upsampled downlink baseband modulated signal with the Nth order power series kernel comprises filtering the time delayed, upsampled downlink baseband modulated signal with the Nth order truncated Volterra series kernel.
