Abstract
A new structure of the subband acoustic echo canceller (AEC) is propos ed. It introduces no delay in the transmission line. Using the new str ucture 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 ha rdware implementation of the proposed subband AEC is also presented in this brief.
