DESIGN A NON-COHERENT MULTI-CARRIER CHAOTIC SYSTEM BASED ON GENERALIZED CARRIER AND PERMUTATION INDEXES MODULATION MECHANISM

Résumé fourni par la source

This study introduces a novel system called Generalized Joint Permutation-Carrier Index Modulation Based MC-DCSK (GJPC-IM-MCDCSK) aimed at enhancing energy efficiency, spectral efficacy, and data transmission rates of GCI-DCSK technology by generating and utilizing permuted forms of the reference chaotic series with quasi-orthogonal properties to distribute the modulated bits across each operational carrier. Furthermore, rather than employing correlation detection, the receiving end of the proposed system utilizes greedy detection to streamline the process. Evaluating the data rate, spectral efficiency, and complexity of the proposed GJPC-IM-MCDCSK system against GCI-DCSK, CI-DCSK1, and MC-DCSK technologies illustrates the superior performance of the recommended design. To illustrate the proposed design's superiority, the simulated Bit Error Rate (BER) performance is evaluated for the GJPC-IM-MCDCSK scheme and compared with the GCI-DCSK, CI-DCSK1, and MC-DCSK systems under AWGN and multipath Rayleigh fading channels.
