Abstract
In this work, an echo cancellation scheme using a variable step-size Normalized Least Mean-Square (VSS-NLMS) adaptive algorithm is proposed. This work shows that the use of the VSS-NLMS algorithm will eliminate much of the trade-off between residual error and speed of convergence existing with the fixed step-size NLMS algorithm and therefore resulting in an improved performance.
