【Abstract】 This paper studies the narrowband interference suppression algorithm based on threshold detection in transform domain, and a novel adaptive multi-threshold narrowband interference detection algorithm is proposed. Theoretical analysis and simulations prove that this algorithm has good performance in suppressing the narrowband interference in DSSS signal.更多还原
