A New Receiver for Chaotic Digital Transmissions: The Symbolic Matching Approach
نویسندگان
چکیده
— Chaotic digital transmissions have recently emerged as a way to improve the security and privacy of digital transmissions. In this paper, we propose a new approach to estimate the transmitted symbols on the receiver side. This approach, that we call “Symbolic Matching”, consists in matching vectors built from the received signal with a symbolic model of the chaotic oscillator trajectories. Simulation results are also provided and they show that low error rates are obtained. Key-Words : — Chaos, Digital Transmissions, Communications, Receiver, Symbolic Matching

A New Approach to Detect Congestive Heart Failure Using Symbolic Dynamics Analysis of Electrocardiogram Signal
The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...

متن کاملA Robust Secondary Secure Communication Scheme Based on Synchronization of Spatiotemporal Chaotic Systems
This paper deals with the synchronization of spatiotemporal chaotic systems and presents a new robust secondary chaotic secure communication system for digital signal transmissions which can recover digital signal even though the transmitted signal is influenced by limited noise. The transmitter terminal and the receiver terminal both contain a spatiotemporal chaotic system and a hyperchaotic s...
متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...

Realism not only has introduced way of thinking but also has discussed a different way of expression in mid-nineteenth century in west and despite its existence has experienced new forms during its stages of development and metamorphosis. Symbolic realism has been discussed as a realistic technique in art and literature style within this through this method, realism and symbolism make contradic...
