Acoustic echo cancellation (AEC) algorithms are widely used in communication devices. One of the main design problems is double-talk issue. The recursive prediction error (RPE) algorithm based on autoregressive (AR) model has been proven to be more attractive to traditional approaches. However, it adapts too fast in double-talk which may cause the algorithm to diverge. A variable step size (VSS) approach is developed to tackle the problem. On the assumption that prediction error is more than 10doi:10.2991/citcs.2012.231 fatcat:geb32lbj7faojaqosobqqpfkwa
