摘要
本文主要研究频域窄带抗干扰算法在北斗三代新体制信号中的应用。通过选择合理的窗函数及FFT变换点数,通过自适应门限检测及频域过门限置零,可以较好的对干扰信号进行抑制。通过对单干扰、三干扰抑制的仿真,验证了算法在新体制信号抗窄带干扰中的性能。
This paper focuses on the application of frequency domain narrowband anti-jamming algorithm in Beidou signal in the three generation.Through the reasonable choice of window function and FFT transform points,the adaptive threshold detection and zero frequency threshold value method can be used to suppress interference.The performance of the new algorithm against narrowband interference is verified by simulation of single and three-interference suppression.
