A Chaos-based Spread Spectrum Communication System
نویسندگان
چکیده
We describe the design and CMOS implementation of a baseband spread-spectrum communication system using chaotic signals for spreading digital data. The communication system uses a new chaotic modulation scheme called M-DCSK (Modified Differential Chaos Shift Keying). The M-DCSK scheme and its characteristics are analyzed for single user and multi user applications. Results from a VLSI implementation are also presented. Keywords—Chaos, Communication, CMOS, DCSK, M-DCSK, Multiple access.

Co-Existence of Chaos-Based Communication Systems and Conventional Spread-Spectrum Communication Systems
This paper studies the performance of selected chaos-based systems which share their frequency bands with conventional spread-spectrum systems. Such a scenario may occur in normal practice when chaos-based systems are introduced while the conventional systems are still in operation. The particular chaos-based systems under study are the coherent chaosshift-keying (CSK) system and the non-cohere...

A new spread spectrum communication system utilizing chaotic frequency modulation of sinusoidal signals is discussed. A single phase lock loop (PLL) system in the receiver is used both to synchronize the local chaotic oscillator and to recover the information signal. We study the dynamics of the synchronization process, stability of the PLL system, and evaluate the bit-error-rate performance of...

Chaotic signals typically have broadband spectrum. This property is desirable for applications that require robustness against interference, jamming and low detection probability. Those issues have been addressed by traditional communication systems by using spread spectrum and frequency hopping modulations. In chaos-based communications the broadband chaotic signal is generated at the physical...
