Abstract
A communication circuit arrangement includes a first kernel dimension filter circuit configured to apply a first kernel dimension filter to a first input signal to estimate a first kernel dimension interference signal from a first amplifier, a second kernel dimension filter circuit configured to apply a second kernel dimension filter to a second input signal to estimate a second kernel dimension interference signal from a second amplifier, a joint delay tap dimension filter configured to apply 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 a cancelation circuit configured to remove the estimated joint interference signal from a received signal to obtain a clean signal.
