摘要: 本文對基于FIR濾波器的信號分解和合成技術(shù)進行了研究,特別對其中的關(guān)鍵環(huán)節(jié)數(shù)據(jù)的擴展方法進行了深入分析,指出了傳統(tǒng)方法中存在的問題,并在傳統(tǒng)數(shù)據(jù)對稱擴展方法的基礎(chǔ)上給出了新方法。

Abstract: In this paper, the signal decomposition and synthesis technique based on FIR filters have been studied, the different data extension methods included in convolution procession have been investigated in detail, the problem involved in conventional symmetric extension method has been reported, the new symmetric extension method has been given. The experimental results show the new method performs better than the conventional methods. -
