摘要
Abstract
Direct sequence spread spectrum technology has important significance in satellite communication and military tac?tical communication by extending the signal bandwidth to achieve anti-interference and anti-interception. In this paper,by estab?lishing a spread spectrum communication system,the relationship between the bit error rate and the signal-to-noise ratio of the spread spectrum communication system is simulated under single-frequency sine wave interference. The simulation results show that the spread spectrum method can improve the signal-to-noise ratio of the communication system and suppress the single-tone in?terference in the communication system to some extent.关键词
