摘要：
The problem of separation of an observed sum of chaotic signals into the individual components is considered in the presence of noise. A noise threshold is. found, above which high-quality separation is impossible. This effect is shown to be associated with the information content of chaotic signals and a theoretical estimate is given for the threshold. A method For signal separation is proposed, which uses iteration of the chaotic sources equations in reverse time. The method allows to approach the theoretical limit threshold.
