摘　　要：本文研究了自适应滤波技术在扩频通信中的窄带干扰抑制作用，针对当前自适应滤波器在实际中存在的数值稳健性问题作了深入详细的分析，为此提出了一种新的组合滤波器模型的解决方法，具体以中心抽头的自适应横式滤波器为基本滤波器结构，在此基础上构造出新的组合滤波器结构，并在理论与实践上对两者作了分析对比。In this paper,the application of adaptive technique for narrowband suppression in SpreadSpectrum (SS) communication is discussed and its' numeric robustness is analyzed. In order to increase the converge rate and improve the output signal noise ratio, we proposed a combined filter mode and constructed a new combined adaptive filter based on a interpolator filter. Finally, the interference suppression ability of both basic adaptive filters and its combined counterparts is compared in theory and in practice.
