acoustic impulse 中文意思是什麼
acoustic impulse
解釋
聲脈沖-
Fir ( finite impulse response ) filter is one of the basic algorithms for digital signal processing, which is a kind of important lti discrete - time system, widely used in acoustic processing and image processing area
Fir ( finiteimpulseresponse )濾波器是數字信號處理的基本演算法之一,是一類較為重要的線性時不變系統,廣泛應用於聲音、圖像處理等現代通信技術中。 -
The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds, the system has to be adaptive, and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing
但由於聲回授通道的特殊性和復雜性,普通的自適應演算法無法滿足要求,必須採用一些十分復雜的演算法,這樣一來,實時性的問題變得十分突出。快速lms newton演算法的提出,給自適應聲回波對消問題的解決開辟了新的途徑。該演算法集lms演算法的簡單易行性和newton演算法的快收斂性為一體,是一種非常有應用前景的自適應演算法。
