一種脈沖噪聲中的韌性恒模算法及其穩(wěn)定性分析

A Robust CM Algorithm in Impulsive Noise Environment and Its Steady-State Analysis

  • 摘要: 由于無線信道的噪聲表現(xiàn)出脈沖性特征,常規(guī)恒模波束形成器的性能出現(xiàn)退化。該文引入 穩(wěn)定分布作為信道脈沖噪聲的模型,提出一種廣義化的韌性恒模波束形成器。以分?jǐn)?shù)低階統(tǒng)計(jì)量為工具分析了該韌性恒模波束形成器在脈沖噪聲干擾下所能達(dá)到的穩(wěn)定狀態(tài)。數(shù)值模擬對分析結(jié)果進(jìn)行了驗(yàn)證。
