A NARROWBAND INTERFERENCE CANCELLER FOR A DIRECT-SEQUENCE SPREAD-SPECTRUM COMMUNICATIONS SYSTEM
摘要
A system for canceling contaminating narrowband interference for a wideband DSSS receiver by weighting a channelized copy (56) of the signal of interest in accordance with the result of a correlation between a narrowband copy (66) of the channelized signal of interest centered around the center frequency of the contaminating narrowband interference and a narrowband copy (68) of a wideband feedback signal centered around the center frequency of the contaminating narrowband interference by injection of the weighted narrowband copy (106) of the channelized signal into a received signalpath, cancellation of the narrowband interference is achieved.
