AN HB WEIGHTED ADAPTIVE TIME DELAY ESTIMATION
-
摘要: 本文提出了一種HB加權(quán)的自適應(yīng)時(shí)間延遲估計(jì)方法。這種方法不依賴于輸入信號和噪聲的先驗(yàn)知識,具有較高的估計(jì)精度和收斂速度,適用于低信噪比下的時(shí)間延遲估計(jì)。

Abstract: This paper proposes an HB weighted adaptive time delay estimator. The theoretical analysis and the computer simulation show that this new method does not depend on the knowledge about input signals and it has a higher precision and faster convergence speed. Under low SNR conditions, the performances of this method are better than those of LMS TDE obviously. -
