Separation of a sum of chaotic signals corrupted by Gaussian channel noise into the components with a method based on chaotic synchronous response is discussed. In order to establish the response, a procedure of iterating the maps, inverse to the maps that generate the chaotic signals, is proposed. The approach is shown to provide a considerable improvement of the noise stability of separation in respect to other methods.
