摘　　要：直扩序列扩频通信具有隐蔽性,抗干扰能力强的特点。但对各种人为的大功率窄带干扰却无能为力。采用窄带干扰抑制技术,是抗各种人为干扰的一种有效手段。本文介绍各种干扰的抑制技术。DSSS has the ability of cover-up and interference rejection. But it does not do well with the interferences of man-made. Narrow-band interference rejection techniques are available ways to reject the interferences of man-made. In this paper, the high-power interference rejection techniques are systematically described.
