IntroductionIn the communication systems, echo and noise will seriously affect speech communication quality, such as IP telephone, videophone and hand-free digital cell phone systems etc.
引言在通信系统中，例如IP电话、可视电话及免提数字蜂窝电话系统中，回声和噪声会严重影响通信质量。
Fractional delay filters are applied to a wide range such as communications, speech processing, echo cancellation, etc.
分数延迟滤波器广泛用于通信，语音处理，回声消除等。
NLMS (normalized least mean square) algorithm is widely used in echo canceller. However, due to high correlation of speech signals, the performance of echo canceller based on NLMS is depressed.
NLMS算法是回声消除器中最常用的算法之一，然而语音信号的强相关性使NLMS(归一化最小均方)算法的收敛速度变慢。
When he had finished his speech, his audience cheered him to the echo.
他的演讲一结束，听众就对他大声喝彩。
