- 中文摘要: 適應性濾波器已被廣泛地應用在訊號處理上,列如:消除雜訊,消除回音,系統辨識,陣列訊號處理等。鑑於微程式方法的許多優點,本篇論文就以微程式的方法及用硬體元件設計並製作了一個可程式化的適應性濾波器。並以最小均方值演算法(LMS)充當適應性演算法則。我們將所製作出的濾波器規劃成適應性雜訊消除器及適應性波束構成器,硬體實驗的結果還令人滿意。
- 英文摘要: Adaptive filters are well applied to many fields, such as noise cancelling, echo cancelling, systemidentification, and array signal processing (Widrow et al,1967,1975). In this study, due to its advantages,the microprogramming approach was employed to design and implement a programmable adaptive filterin hardware. The adaptive algorithm used, was the well-known least mean square (LMS) algorithm. Theproposed adaptive filter could be programmed as an adaptive noise canceller or adaptive beamformer. Theexperiment results are satisfactory.
