【摘要】 通信设备和系统生存于纷繁复杂的电磁环境之中 ,面临的干扰日益严重 ,许多时候由于受到扩频带宽的限制 ,仅靠扩频增益已不足以对干扰进行抑制 ,特别是在强窄带干扰的场合 ,必须采取其它措施进一步提高扩频通信的抗干扰能力。综述并分析了许多重要的抗窄带干扰技术。

【Abstract】 Communication equipment and systems often operate in complex electromagnetic surroundings, and are faced with more and more serious interference. Many a time, restricted by the spread spectrum(SS) bandwidth, they can not reject the external interference efficiently only by the SS gain. Thus some other methods are required to improve the insterference rejection capability the SS communication systems. Especially in the presence of strong narrow-band interference, it is of much necessity to reject the narrow-band interference. Because of the reasons above, many important techniques to reject narrow-band interference are described and analyzed.
