| Abstract(in English) | This paper proposes a stereo echo canceller with simultaneous input-sliding and sliding-period control. Periodic delays with different phases in two channels provide an additional condition for echo cancellation, leading to faster convergence. Signal sliding in both channels guarantees symmetrical shifts of a sound image around the original position for better subjective quality of the far-end signal. Sliding artifacts are made less noticeable by sliding-period control with more slidings for less interchannel correlation of the input signals. Simulation results show that the convergence speed of the proposed echo canceller is 33% faster than that of the echo canceller with single-channel input sliding. Subjective evaluation results demonstrate that the proposed echo canceller achieved a 0.48 higher grading difference in the ITU-R five-grade impairment scale than single-channel input sliding with a statistically significant difference. |
