An algorithm using for the echo canceller.
Le Thanh Ha, Nguyễn Thị Lan Hương · Journal of Computer Science and Cybernetics · 2012
In the telecommunication systems of the integrated servises digital communications network, in order to guarante the transmission quality, they usually used echo canceller.However, because the dynamic band of the input signal is rather large and often nonstationary so that if you want to use LMS, RLS there is constant control step-size that the echo canceller works unstable.This paper will introduce an algorithm using for the echo canceller satisfying an input signal to be wide dynamic band.T6m t~t.Trong cac h~thong vi€n thOng cda mang so da dich vu, d€ dam bdo chat hro-ng truyen d&n, ngu'o'i ta thirong s11:dung b9 gat hoi am.Tuy v~y, VI giai d9ng cd a tin hieu vao tiro'ng d5i lo'n v a thiro'ng la khOng dirng, VI v~y neu su' dung cac thu~t toan LMS, RLS c6 cO-bu•&c di"eu khi€n khOng thay dO'i thl b9 gat hoi am lam viec khcng O'n dinh.
