Abstract

A system, method, and computer program product for baseband removal of narrowband interference contained within UWB signals in a UWB receiver. The RFI is extracted from the UWB signal by employing a filter (110) that is matched approximately with the RFI in the baseband signal, extracting RFI, and passing the desired data signal unscathed.
