چکیده انگلیسی
The proper control of acoustic echoes is of vital significance in modern communication systems. Acoustic echoes are commonly combatted by means of acoustic echo cancellation. A critical issue in acoustic echo cancellation is the control of adaptation of the echo cancellation filter with the possible presence of near-end speech activities. In this paper, a novel echo cancellation structure is proposed. The proposed structure makes use of two parallel adaptive filters. Echo of the two parallel adaptive filters is tailored for a specific operating situation. By so doing, the contradicting requirements of robustness against near-end disturbance and fast convergence and tracking speed are achieved simultaneously.
