Implementation of Robust Acoustic Echo Cancellation in the Short Time Fourier Transform Domain Using Adaptive Filter

摘要

This paper focus a robust acoustic echo cancellation method and used in the short Fourier Transform (STFT) domain using adaptive digital cross band filters. The AEC system using STFT domain method. This system is compared with Modular systems of AEC.it is normally requires several application of the Discrete Fourier Transform (DFT) and Inverse Discrete Fourier Transform (IDFT). The New Robust method of AEC (RAEC) allows for Stable filters and Continuous updating during double talk condition without freezing the adaptive filter which RAEC using STFT domain method have been investigated in the separate studies for this work we propose a novel algorithm that combines the advantages of both approaches for updating adaptive filters during double talk. The Experimental results are comparing with the Corresponding cross band filters output and it shows improved performance in terms of echo reduction and the predicted quality sound and human speech.
