CDSK Modulator and Demodulator System Based on FPAA Technology

Abstract

Experts have been concerned about the security of digital communication systems and the reduction of interception in recent years. Because of its inherent characteristics and high efficiency in encoding information, chaotic signals can play a significant role in this respect. A dynamically reconfigurable FPAA AN231E04 from Anadigm is used to implement of Correlation Delay Shift Keying (CDSK) communication system. The FPAA chip can be used in almost any electronic hardware for analog system implementations. It permits the experimental selection or amendment of the system structure to achieve its specific properties. The performance of the Rossler oscillator was evaluated via MATLAB Simulink environment. The practical implementation demonstrates and validates chaotic dynamic behavior. The effect of Additive White Gaussian Noise (AWGN) on the performance of the proposed CDSK systems was studied. Under the impact of the AWGN channel, the performance efficiency of the suggested CDSK and noncoherent differential chaos shift keying (NC-DCSK) systems were examined. The CDSK bit transfer technique is safer than the NC-DCSK bit transfer technology. The power consumption of the proposed system is (only 763±18 mW) according to performance studies.
