Interference canceller for the protection of direct-sequence spread-spectrum communications from high-power narrowband interference

摘要

A system for canceling contaminating narrowband interference for a wideband DSSS receiver by weighting a channelized copy of the signal of interest in accordance with the result of a correlation between a narrowband copy of the channelized signal of interest centered around the center frequency of the contaminating narrowband interference and a narrowband copy of a wideband feedback signal centered around the center frequency of the contaminating narrowband interference.
