echo cancellation

基本解释

So acoustic echo cancellation (AEC) technique has become a hot issue of competition in the famous communication company all over the world.
因此，回波消除技术也就成为世界各大通讯公司竞争的热点技术之一。
This paper describes a Quasi-Kalman recursive echo cancellation algorithm for fast acquisition of echo paths on two-wire full-duplex data transmission system.
本文提出的准卡尔曼回波消除器递归算法，能够快速捕捉二线全双工数据传输系统中回波信道的脉冲响应。
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.
随着回声消除技术的发展，对回声消除研究的重点已由电路回声的消除转向了声学回声。
