| Abstract: | In the mobile communication domain, adaptive echo cancellation has been widely used with the algorithm of adaptive echo cancellation as its key technology. Quality of algorithm will have direct effect on the result of cancellation, and good algorithms will reduce system complexity and lower the cost of product. The paper gives an analysis on the key algorithm of adaptive echo cancellation NLMS , algorithm of double talk detection, and algorithm of nonlinear processing. |
