摘要: 該文分析基于門限檢測的直接序列擴頻通信系統(tǒng)變換域窄帶干擾抑制技術，提出一種基于自適應多門限窄帶干擾抑制算法，并對其性能進行詳細分析，理論分析和數(shù)字仿真結果表明，該算法可有效抑制直擴通信系統(tǒng)中的窄帶干擾，并且相對于傳統(tǒng)的門限檢測算法，有自適應性強，門限設計簡單等優(yōu)點。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.
