带残余回声处理的回声消除算法

Acoustic Echo Cancellation Algorithm with Residual Echo Cancellation

提出一个能在实际环境中使用的回声消除算法,利用子带回声消除的特点,结合人耳听觉掩蔽效应,提出带有残余回声处理的回声消除算法。仿真数据和实际应用证明,该算法能够有效改善回声消除的效果。

An acoustic echo cancellation algorithm used in real environment is proposed. Based on the subband acoustic echo cancellation, a residual echo cancellation technique is presented by using the masking properties of human auditory system. Simulation and application results show that the proposed algorithm can eliminate the echo to a satisfactory degree.
