摘要:

在简要总结窄带干扰抑制方案和技术的基础上,介绍了一种基于加窗的频域自适应窄带干扰抑制方法,该方法是在离散傅里叶变换(DFT)技术、自适应门限算法的基础上形成的,简单有效,可靠实用。软件仿真及硬件实测结果均证明了该方法的可行性及有效性。

Abstract:

Based on summarizing narrow band interference suppression scheme and technique,this paper describes a window-based adaptive narrow band interference suppression method for frequency domain.The method is derived from the DFT and adaptive threshold algorithm,and it is simple and effective as well as reliable and practical.Software simulation and actual hardware test result have verified the feasibility and effectiveness of the method.
