This paper presents a new approach for network echo cancellation, based on a combination of normalized least mean square (NLMS) and proportionate NLMS (PNLMS) adaptive filtering algorithms. The PNLMS has a good initial convergence region (that is, the first echo path coefficients are fast adapted), but for long path echo the last coefficients are slowly(More)
