echo cancellation

基本解釋

So acoustic echo cancellation (AEC) technique has become a hot issue of competition in the famous communication company all over the world.
因此，回波消除技術(shù)也就成為世界各大通訊公司競(jìng)爭(zhēng)的熱點(diǎn)技術(shù)之一。
This paper describes a Quasi-Kalman recursive echo cancellation algorithm for fast acquisition of echo paths on two-wire full-duplex data transmission system.
本文提出的準(zhǔn)卡爾曼回波消除器遞歸算法，能夠快速捕捉二線(xiàn)全雙工數(shù)據(jù)傳輸系統(tǒng)中回波信道的脈沖響應(yīng)。
With the development of echo cancellation technologies, the research emphases for echo cancellation has already been turned from network echo to acoustics echo at present.
隨著回聲消除技術(shù)的發(fā)展，對(duì)回聲消除研究的重點(diǎn)已由電路回聲的消除轉(zhuǎn)向了聲學(xué)回聲。
