摘要：Nowadays, in the field of communications, AEC (acoustic echo cancellation) is truly essential with respectto the quality of multimedia transmission. In this paper, we designed and developed an efficient AEC basedon adaptive filters to improve quality of service in telecommunications against the phenomena of acousticecho, which is indeed a problem in hands-free communications.The main advantage of the proposed algorithm is its capacity of tracking non-stationary signals such asacoustic echo. In this work the acoustic echo cancellation (AEC) is modeled using a digital signalprocessing technique especially Simulink Blocksets. The algorithm’s code is generated in Matlab Simulinkprogramming environment. At simulation level, results of simulink implementation prove that modulebehavior is realistic when it comes to cancellation of echo in hands free communication using adaptivealgorithm.
