Optimum Design for Correlator-Type Receivers in Chaos-Based Digital Communication Systems
نویسنده
چکیده
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 generators can be different or identical but with different initial conditions. The theoretical symbol error rate (SER) of the system under a noisy environment is derived. Simulations are also carried out to verify the theoretical SER. Finally, the results are compared with those obtained from systems using suboptimum receivers, and those from a conventional amplitudeshift-keying system.

Optimum Correlator-Type Receiver Design for CSK Communication Systems
In a chaos-shift-keying (CSK) digital communication system, correlators followed by a comparator are typically used for coherent detection of the signal. Such a detection method, however, does not take the temporal variation of the bit energy into consideration. In this paper, an optimum detection for a binary CSK system is derived, taking into account the temporal variation of the bit energy f...

متن کاملA Chaos-Based Communication Scheme Using Proportional and Proportional-Integral Observers
In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...
