Robust signed regressor PNLMS method and apparatus for network echo cancellation |
摘要 |
The invention is a method and apparatus for performing echo cancellation utilizing a Proportionate Normalized Least Mean Squares (PNLMS) algorithm having a high convergence rate and low complexity. The invention utilizes a proportional step-size adaptive algorithm which utilizes the signs of the regressor rather than the regressor value itself in the gradient calculation.
