INTEGRATED APPROACH FOR ENDOSCOPIC DETECTION OF CANCER
Not Available There is a need in both commercial and military applications for digital transmission methods that can operate at high data rates (several megabits per second end-user rate) in multi-user environments. Existing communication methods will be severely stressed by the requirements of such an environment: Propagation anomalies such as multipath fading and interference will require intensive digital processing to mitigate their effects. By developing a digital signaling approach based on the control of the natural complexity of the chaotic behavior of RF devices, alternative solutions to these fundamental problems emerge. We will develop in this proposal an approach for controlling an RF chaotic oscillator that preserves the natural properties of the waveform while encoding digital information at the highest rate possible. We call this approach dynamics-based signaling, and it is based on the fundamental connection between dynamics and communication theory and symbolic dynamics. We will also investigate frequency scaling, and the advantages of this approach over traditional methods for digital communication. We will show that our method provides extremely fast, smooth switching between unstable periodic orbits.
