抗窄带干扰应用中自适应技术的研究
daptive Technology Research in Attenuation of Narrowband Interference
在实际通信系统中，当系统存在较强窄带干扰时，系统性能会产生严重恶化。为了抑制系统中的窄带干扰，可以使用自适应滤波器。本文首先介绍了最小均方（LMS, Least Mean Squares）自适应算法和递归最小二乘（RLS, Recursive Least Squares）自适应算法的基本原理，对两种算法进行了分析，并且实现了两种算法抗窄带干扰的仿真。根据matlab仿真结果，比较了两种自适应算法的性能差异。
In general cummunication systems, strong narrowband interference will cause the degradation of performance significantly. Adaptive filters can be used to suppress narrowband interference. In this paper, the fundamentals of Least Mean Squares(LMS) algorithm and Recursive Least Squares(RLS) algorithm are introduced and comparatively analyzed firstly. Then, both algorithms are applied to suppress narrowband interference in computer simulation. The performance differences are disscussed in the end.
