Considered an adaptive echo canceller covered invariant feedback. The research on a new method of invariant echo canceller adaptation, produced modeling of processes in the adaptive echo canceller scheme, created and produced by the simulation model processes duplex data transmission system extending circuit adaptation, using the environment MATLAB, presented charts and formulas necessary for the recognition of the system workable. The obtained results show the dependence of the mean squared error (MSE), the variance of the white noise signal in various forms, confirm previous indications, i.e. prove that the proposed scheme adaptive echo canceller is workable invariant under mismatch differential system under the action of interference in the form of white noise.
