optimal nonlinear filtration of chaotic oscillations
receiver synchronization with unknown parameters
The synchronization problem of master-slave type chaotic oscillations is considered when parameters of a receiver synchronization block are different from the parameters of a transmitter generator. A mathematical model for unknown parameters of the received signal is proposed; also synchronization algorithms are presented for the case of signal reception in the additive Gaussian noise. On the example of chaotic sequence described by the M. Hénon mapping, it is shown that these algorithms allow implementing the adjustment of receiver parameters virtually under any values of the initial mismatch and at a random ratio of signal transmission from a transmitter to a receiver.
