Abstract

A new structure of the subband acoustic echo canceller (AEC) is proposed. It introduces no delay in the transmission line. Using the new structure and a simplified weighted overlap-add method, an acoustic echo canceller is designed. The results showed that the designed system has good echo reduction and is stable in nonstationary environments. A hardware implementation of the proposed subband AEC is also presented in this brief.
