TL;DR: The application of high-order adaptive filters to the problem of acoustical echo cancellation with particular application to hands free telephone systems is discussed and a means to achieve robust performance is described.
Abstract: We have discussed the application of high-order adaptive filters to the problem of acoustical echo cancellation with particular application to hands free telephone systems. We described a means to achieve robust performance. We further presented methods for reducing computational complexity that allow implementation in low-cost, fixed-point digital signal processors. Progress in technology will allow the use of more sophisticated algorithms at lower cost in the near future.

TL;DR: Analytical examples are used to show that a widely used criterion for the ESP, the spectral radius of the weight matrix being smaller than unity, is not sufficient to satisfy the echo state property.

TL;DR: These echoes can be used to place digital identi cation tags directly into an audio signal with minimal objectionable degradation of the original signal.
Abstract: Homomorphic signal processing techniques are used to place information imperceivably into audio data streams by the introduction of synthetic resonances in the form of closely spaced echoes These echoes can be used to place digital identi cation tags directly into an audio signal with minimal objectionable degradation of the original signal

TL;DR: In this article, a phase-cycling scheme is proposed to prevent spectral distortion due to misset pulse lengths, and the theoretical single pulse and echo distortion factors are demonstrated to differ from those which were determined for quadrupolar echo spectroscopy.
