The aim of this paper is to design and simulate an AEC in order to enhance the quality of speech disturbed by echo phenomenon. Therefore, in order to design the normalized adaptive AEC, we have used digital signal processing techniques, especially Simulink embedded functions. Effectiveness of the suggested AEC using adaptive normalized algorithm was verified using Matlab/Simulink software. Finally, our AEC has been tested by using ERLE criteria and the analysis results show more efficiency according to ITU-T recommendation G.168.
