Echo Cancellation in Voip using block-based Adaptive Filter

Department of ECE, St. Peter's Engineering College, Medchal, Hyderabad, Telangana, India

Abstract

Acoustic Echo Cancellation (AEC) has ended up being a need in the present conferencing framework keeping in mind the end goal to improve the quality of audio of hands free communication. Over the most recent couple of years, many researchers and manufacturers have developed various AEC algorithms for telecommunication systems so as to improve their services. Over the most recent couple of years, many researchers and manufacturers have developed various AEC algorithms for telecommunication systems so as to improve their services. Many variables impact the parameters of an AEC framework, for instance computational unpredictability, memory utilization and so on. This paper proposes state-space model and the related technique for the divided square sifting structure which is particularly applicable in practice. This philosophy allows the utilization of extensively longer channel lengths and for the adaptable plan and execution of AEC devices for VoIP applications.
