Title
An improved IPNLMS algorithm for echo cancellation in packet-switched networks
Abstract
We present an improved adaptive echo cancellation algorithm designed for use with sparse echo path impulse responses such as arise from packet-switched networks. The new approach implicitly segments the impulse response into 'active' and 'inactive' regions, and employs different proportionate updating in each region. An efficient partial updating scheme is then formulated for the new algorithm. Evaluation results are presented to compare the new algorithm against three existing methods in terms of convergence and computational complexity. The results show that the new algorithm outperforms the best existing technique and has lower complexity.
