Abstract	:	In this work, an echo cancellation scheme using a variable step-size Normalized LeastMean-Square (VSS-NLMS) adaptive algorithm is proposed. Many algorithms pro-posed in the literature for this application were not given much attention i n real-timeapplications due to their heavy complexities. The NLMS algorithm however, is givenmuch attention because it has a good balance between performance and complexity.Conventional echo cancellers using a &ed step-size algorithm, usually results in atrade-off between residual error and speed of convergence. The variable step-sizeNLMS algorithm presented in this work gives an improved performance, eliminatingsuch trade-off. The step-szze vclriation makes it possible for the algorithm to con-verge faster and at the same time, yielding a lower,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
