摘要
Abstract
This paper proposes a adaptive multi-threshold narrowband interference suppression algorithm based on comparing statistical mean of Coefficient of Variation (CV).The algorithm use statistical mean of CV as switching metric, the CV metric turn to matched filter when Jammer-to-Signal Ratio (JSR) is low, and turn to adaptive multi-threshold algorithm for narrowband interference suppression when the JSR is high.Theoretical analysis and simulation results show that the CV is effective as switching metric and that the algorithm has better adaptive capability in suppressing narrowband interference in DSSS.关键词
