Abstract In this paper, the methodological aspects for the design of mixed-signal map-configurable chaos generators are presented. Such techniques have been applied in the integration, embedded in a complete FM-DCSK modem, of a chaos generator which achieves 10 bits resolution at a maximum clock frequency of 20Mhz, from a 3.3V power supply.

HARDWARE IMPLEMENTATION OF A TENT MAP-BASED CHAOTIC GENERATOR Cristian-Iulian RÎNCU Vasile-Gabriel IANA

In the last ten years the interest for chaos has increased due to the great resources represented by the dynamical chaotic systems which can be used to assure secure and wide band communications. Also, chaotic systems are widely used to design analog and digital blocks for communication systems. In this paper we present some aspects regarding the hardware implementation of one well-known digita...

Optimum Design for Correlator-Type Receivers in Chaos-Based Digital Communication Systems

In chaos-based digital communication systems, a correlator is normally used in the coherent detection of the signal. In this paper, an optimum design for such correlatortype receivers is presented. A chaos-based digital communication system with one chaos generator has been used to exemplify the performance of the design. The design can be extended to systems with multiple generators, where the...

A chaos tracker applied to non-coherent detection in chaos-based digital communication systems

In chaos-based communication systems, parameter variation in the chaos generator and additive channel noise represent two practical problems that are hard to sol*. For chaos-based digital communication, non-coherent detection has the advantage that the receiver does not need to reproduce the same chaos basis function that has been generated in the transmitter. SUC h reproduction typically requi...

Integrated Chaos Generator for Chaotic Communication Syste..

This paper analyses a method by which chaos is generated using electronic circuits. The chaos generator required for this purpose is based on utilizing the one dimensional piece wise linear Bernoulli Shift map. The iterative map is realized using a feedback system consisting of programmable amplifier and a unity-gain sample-and-hold amplifier. The sample and hold amplifier provides necessary de...

Transmission of Digital Chaotic and Information- Bearing Signals in Optical Communication Systems

A new proposal to have secure communications in a system is reported. The basis is the use of a synchronized digital chaotic systems, sending the information signal added to an initial chaos. The received signal is analyzed by another chaos generator located at the receiver and, by a logic boolean function of the chaotic and the received signals, the original information is recovered. One of th...
