Correlation methods of estimation parameters acoustic signals and interference in telecommunications

The questions of modeling and methods of acoustic signals in telecommunication systems audio exchange in which there may be the presence of a high level of acoustic noise and disturbance. In particular, research regarded correlation methods and long-term delay parameter estimation and compensation algorithms and schemes echo subscriber units and with single-band multi-band signal processing. The algorithms for estimating the echo parameters and adaptive compensation can reduce the number of filter taps and increase the speed of their adjustment, improve the compensation results.
