Abstract
In this paper, an adaptive echo canceller based on unbiased equation error adaptive IIR notch filter for the echo cancellation in telephone network is presented. The unbiased equation error algorithm employs the bias removal techniques to remove the bias existing in the estimated parameter, resulting in obtaining good estimate of parameter for the echo canceller. The computer simulation results in terms of echo return loss enhancement (ERLE) are provided to confirm the performances of the presented adaptive echo canceller. © 2008 IEEE.
