Abstract
A wideband receiver comprises a comb limiter combiner wherein the limiting is conducted by digitization and frequency excision in the frequency domain. The received signal is divided up into sub-bands by a bank of bandpass filters having contiguous pass bands spanning the entire receiver range. In each sub-band the band limited signal is digitized and subjected to digital signal processing. A threshold is set such that any frequency with a magnitude that exceeds the threshold is excised in the frequency domain. When converted back to the time domain, the high-power interference frequencies will no longer be present, thereby leaving only the low-power noise and the desired signal.
