Abstract:
A method for communicating at least one information signal from a transmitter to a receiver comprising the steps of:a) providing a transmitter for generating a transmitter signal said transmitter being based on a chaotically varying system;b) modulating at least one electrical parameter in said transmitter with an information signal to generate a chaotically varying modulated transmitter signal including a plurality of states;c) transmitting only a selected portion of said modulated transmitter signal to a receiver, said selected portion including less than all of said states;d) providing said receiver with initial parameter information for said transmitter;e) applying said selected portion of said modulated transmitter signal to an Extended Kalman Filter (EKF) in said receiver; andf) generating an estimate of said information signal with said EKF using only said selected portion of said modulated transmitter signal and said initial parameter information.
