Abstract
For the DS communication system,DS spread spectrum communication within the allocated bandwidth means that the service information to be transmitted is extended to the carrier frequency corresponding to the carrier frequency band allo-cated by the satellite transponder to the shipborne station by the pseudo-random code, and then modulated and frequency-converted Sent to the wireless channel,the receiver at the carrier station by DS despreading processing,the input broadband useful signal spectrum is restored to the original signal bandwidth,while the wider band interference signal spectrum is fur-ther expanded,Narrowband filter after DS despreading module can filter most interference signals[1,2],so as to achieve the suppression of interference by DSSS. However, the interference effects of DSSS systems with different interference patterns are not the same,and the concrete analysis is performed according to the specific interference signal patterns.In this paper,the main analysis for the suppression of coercion:point frequency interference,multi-frequency interference,part of the band interference,full-band interference on the DSSS technology interference analysis.关键词
