In stereophonic acoustic echo cancellation (SAEC) problem, fast and accurate tracking of echo path is strongly required for stable echo cancellation. In this paper, we propose a class of efficient fast SAEC schemes with linear computational complexity (with respect to filter length). The proposed schemes are based on pairwise optimal weight realization(More)
This paper presents a novel stereophonic acoustic echo canceling scheme. The proposed scheme is based on the ideas of “simultaneous use of two different states of inputs [Yukawa & Yamada, IEICE 2004]” and “an accelerating weight technique named POWER [Yukawa & Yamada, EUSIPCO 2004]”. The two states generate two solution(More)
