摘要：Acoustic Echo Cancellation (AEC) has become a necessity in today�s conferencing system in order to enhance the audio quality of hands-free communication systems. In recent years, many researchers and manufacturers have developed various AEC algorithms for telecommunication solutions in order to improve the quality of service. Many factors influence the design of an AEC system, such as computational complexity, memory consumption etc. The aim of this work is to review the most recent acoustic echo cancellation techniques and their applicability for current hands free applications. Therefore, this paper presents AEC systems challenges and comparison between these techniques is also presented.
