Line echo cancellers are widely used in telephony. Most commonly used adaptive algorithm is Normalized Least Mean Squares (NLMS). Unfortunately it has poor performance in double-talk mode. In this paper the performance of NLMS algorithm with Double-Talk Detector (DTD) based on Geigel algorithm is researched. A new robust adaptive algorithm based on NLMS is proposed, and its properties are studied. The DSP based comparison of echo canceller models using NLMS and proposed algorithm is considered.
Keywords: line echo canceller, normalized least mean square algorithm, double-talk detector, misalignment, robust algorithm, digital signal processor.
