基于自適應(yīng)多門限算法的變換域窄帶干擾抑制

Narrow-Band Interference Suppression in Transform Domain Based on Adaptive Multi-threshold Algorithm

  • 摘要: 該文分析基于門限檢測(cè)的直接序列擴(kuò)頻通信系統(tǒng)變換域窄帶干擾抑制技術(shù)，提出一種基于自適應(yīng)多門限窄帶干擾抑制算法，并對(duì)其性能進(jìn)行詳細(xì)分析，理論分析和數(shù)字仿真結(jié)果表明，該算法可有效抑制直擴(kuò)通信系統(tǒng)中的窄帶干擾，并且相對(duì)于傳統(tǒng)的門限檢測(cè)算法，有自適應(yīng)性強(qiáng)，門限設(shè)計(jì)簡(jiǎn)單等優(yōu)點(diǎn)。
    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.
