Abstract :
This paper presents an implementation of an acoustic echo cancellation (AEC) system for the Telepresence environment where high quality speech communication is required. Implemented AEC system consists of the blocks related to pre/post-processing, the partitioned block frequency domain adaptive filter (PBFDAF) with a variable step size. Simulation results using real audio recording with the Telepresence system confirms superiority of the Implemented AEC.
