This paper presents a robust normalized least mean square (nlms) adaptive scheme for echo cancellation. The scheme combines the advantages of the conventional Geigel double talk detector (DTD) with some initiative ideas. The classical nlmsalgorithm is used until the convergence is reached. After that, the controlled nlmsalgorithm is used. The Network Echo Canceller (NEC) is implemented in conformity with ITU-T G.168 recommendation. Experiments show that stable performance is ensured during abrupt changes.
