摘要
Recently, Vaidya and Angadi proposed a new method to find the parameters of Lorenz system in a very rapid manner from synchronizing signal by using its derivatives. In this Letter, we extended it to analysis of Chua's circuit. An example of this approach to decode chaotic shift keying is presented. (C) 2004 Elsevier B.V. All rights reserved.
