Abstract
A communication circuit arrangement includes a signal path circuit configured to separately apply a kernel dimension filter and a delay tap dimension filter to an input signal for an amplifier to obtain an estimated interference signal, a cancelation circuit configured to subtract the estimated interference signal from a received signal to obtain a clean signal, and a filter update circuit configured to alternate between updating the kernel dimension filter and the delay tap dimension filter using the clean signal.
