Abstract: In order to effectively suppress the narrow-band interference in short-wave communications,this paper presents an improved adaptive multi-narrowband lattice notch filters algorithm,which is based on the structure of Gray-Markel notch filter and uses LMS-Newton iteration to update parameters of notch filters.The simulation results show that this algorithm has a good convergence and robustness.

Key words: short-wave communication, narrow-band interference, adaptive, notch filter
