Chaos parameter modulation equalization

The present contribution focuses on a parameter modulation type chaos communication system, using adaptive chaos synchronization. The proposed system is based on discrete-time additive nonlinear emitter and receiver systems. Modulating and recovered signals are quantized, aiming at a digital communication infrastructure. The proposed approach is more efficient than classical counterparts due to its message multiplexing capability. Transmission speed improvement is achieved using linear equalizers, on all multiplexed paths, at the receiver end of the communication system. Simulation results confirm the higher efficiency of the receiver with the proposed equalizer and error analysis leads to solutions for exact data recovery.
