A new nonlinear-filter-based modulation/demodulation technique for chaotic communication

A novel modulation/demodulation technique for digital chaotic communications using nonlinear filtering is proposed. The performance of this technique is compared in simulation with the existing nonlinear filtering based chaotic communication schemes for three different nonlinear estimators. The feasibility of the proposed technique is verified by theoretical analysis and computer simulation. The result is also compared with the theoretical bit error rate performance bound for chaotic communications.
