Abstract: |
For parameter estimation of chaotic telemetry system, chaos synchroniz
ation based parameter estimation between two different time-delayed chaotic syst
ems is investigated. An adaptive scheme is proposed to estimate all the parameter
s of the interested system using a different system. Sufficient conditions for s
ynchronization and parameter estimation are shown analytically according to Kra
sovskii-Lyapunov theory.By using the parameter estimation scheme in chaotic
telemetry signal reconnaissance,the message transmitted can be recovered effect
ively. The proposed scheme can be used
to obtain useful information of chaotic telemetry system between two different
chaotic systems by non-cooperator. Numerical simulations illustrate the validit
y of the scheme. |
