ICA for acoustic echo control

In this paper we propose a new paradigm for acoustic echo control and find a powerful echo cancellation method. We apply independent component analysis for separation of near-end signal from the echo. During double talk the near-end and far-end signals are uncorrelated and the underlying echo is a weighted sum of far-end signals with different delays (echo components). The simulation results obtained are giving a preliminary idea of the results where the near-end signal is separated and, moreover, it is not distorted (no disturbing artefacts appear). The level of echo attenuation is very high, 30-50 dB.
