A robust transform domain echo canceller employing a parallel filter structure

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...

description 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.
