自适应滤波抑制电子设备窄带干扰的研究

Research on using self-adaptive filter technique to suppress narrowband interference of electronic equipment

摘要:

针对电子设备内部、外部普遍存在的窄带干扰问题,提出了采用自适应滤波的手段抑制这种干扰信号的设想,分析了其抑制扩频信号多窄带干扰的性能,并对其做出了理论论证。

Abstract:

An assumption on adopting self-adaptive filter techniques to suppress the narrowband interference that ubiquitously existing inside or outside the electronic equipment is proposed. Its suppression performance to narrow-band interferences in spread-spectrum signal is analyzed, and is demonstrated by theoretic researches.
