چکیده
Nonlinear dynamic based systems that are generated using chaotic sequences are analyzed in this paper. Special attention is given to CSK (Chaos Shift Keying) and DCSK (Differential Chaos Shift Keying) system performances evaluation for maximum likelihood detection using Viterbi algorithm. Originally results, obtained by computer simulation are compared with analytical and simulation results for CSK and DCSK systems with correlation detector. Also, comparation with classical telecommunications systems is given, and problem of chaotic sequences synchronization and orthogonallity are considered.

متن کاملLorenz-based Chaotic Secure Communication Schemes
Secure communication systems employing chaos have recently attracted significant interest. This is partly due to their high unpredictability and simplicity of implementation over conventional secure communications systems. This study presents the implementation of four chaotic modulation techniques employing Lorenz system as chaos generator. The techniques are Chaotic Masking (CM), Chaos Shift ...
متن کاملAnti-Jamming Performance of Chaotic Digital Communication Systems
Among the various modulation schemes proposed for chaos-based digital communications, chaos-shift keying (CSK) and differential chaos-shift keying (DCSK) have been most thoroughly analyzed and considered for practical implementation. One important aspect of performance of any communication system is the ability to resist jamming. This area of study, however, is not available in the literature. ...

In this paper we demonstrate the application of the Frobenius-Perron operator to the statistical analysis of chaotic systems. The Frobenius-Perron operator is the main analysis tool whenever statistical properties of the generated and processed signals are of interest. One important eld of application are systems, where information is located in a particular statistic of the chaotic signal. For...

For lack of empty radio bands, ultrawideband (UWB) radio system allowing reuse of already occupied frequency bands is the only solution to accommodate new wireless data communication services. Two types of UWB carriers are considered here, the frequency-shifted Gaussian pulse and chaotic signal with FM-DCSK modulation. A generalized model of transmitted reference systems is introduced first tha...
