Co-existence of chaos-based and conventional digital communication systems

چکیده
This paper studies the performance of selected chaos-based communication systems whose spectrum overlaps with that of conventional narrowband 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 chaos-shift-keying (CSK) system and the non-coherent differential CSK system, and the coexisting conventional system employs the binary phase-shift-keying modulation scheme. Analytical expressions for the bit error rates are derived and computer simulations are performed to verify the analytical findings. Index Terms — Chaos communication, chaos-shift-keying, differential chaos-shift-keying, binary phase-shift-keying.

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...
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...

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...
متن کاملOptimum 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...
