摘 要: | 近年由于扩频技术具有强的抗干扰能力、隐蔽性、抗多径干扰能力、精确定时和测距,并具有多址能力,所以无论在军事还是在民用方面都受到很大的关注,并且有了很大的发展。为了进一步提高扩频系统的抗干扰能力,将自适应抗干扰技术应用于扩频系统,通过计算机仿真研究了LMS算法的抗干扰性能.结果表明,LMS算法简单,可以应用于扩频系统的前端,对窄带干扰有良好的抑制.

Abstract: | In the resent years, the technology of spread-spectrum attracted great attention because of its ability of anti-interference, privacy, ability of anti-multipath and accurate timing and range. In this paper, the adaptive anti-interference LMS is applied to the spread-spectrum system to improve the performance. The simulation result indicates that LMS is simple and can greatly reduce the narrowband interference. |
