摘要：
Adaptive echo cancellation using the wavelet packed subband decomposition can reduce the computation burden significantely, but suffer from a problem of non-shiftability. An approach to adjust the original wavelet function intend to solve this problem has been proposed in the paper.The relationship between perfect reconstruction (PR) and shiftbility has been disccused also.
