17. A method of performing interference cancelation comprising:
applying a first kernel dimension filter to a first input signal to estimate a first kernel dimension interference signal derived from a first amplifier;
applying a second kernel dimension filter to a second input signal to estimate a second kernel dimension interference signal derived from a second amplifier;
applying a joint delay tap dimension filter to a combination of the first kernel dimension interference signal and the second kernel dimension interference signal to obtain an estimated joint interference signal; and
removing the estimated joint interference signal from a received signal to obtain a clean signal.
