Abstract
A structure for the subband acoustic echo canceler is proposed that avoids filter banks in the sending line and the consequent delay. In this arrangement of the filter banks, the conventional least-mean-square algorithm is modified and an additional adaptive filter is included. Simulation results are given, and a real application is reported
