Optimal Receiving and Estimation Parameters of Pseudorandom Signals of Nonlinear Dynamical Systems

The noise-like signals are widely adopted now in the wideband communications systems as they provide high noise protection of the communications system and the compatibility of information transmission with measurement of object motion parameters in system of moving communications system. Chaotic signals generated of nonlinear dynamical systems are noise-like ones inherently and therefore can be considered as the base for construction of communications systems with high noise protection. With the purpose of development of the pseudorandom signals nonlinear dynamical system optimal receive the problem of construction of functional of maximal likelihood is considered and cross-correlation functions are analyzed an examples of the dynamic chaotic systems of the type Lorenz and Rossler. The base of the suggested algorithm is maximal likelihood method and also presentation of nonlinear differential equations system as the stochastic differential equations systems)
