Design and performance analysis of dual-mode triple-dimensional index modulation differential chaos shift keying system
Given the issues of low transmission rate and poor bit error performance in traditional differential chaos shift keying systems, a dual-mode three-dimensional index modulation differential chaos shift keying (DMTD-IM-DCSK) system was proposed. This system simultaneously utilized time slots, orthogon...

| description | Given the issues of low transmission rate and poor bit error performance in traditional differential chaos shift keying systems, a dual-mode three-dimensional index modulation differential chaos shift keying (DMTD-IM-DCSK) system was proposed. This system simultaneously utilized time slots, orthogonal codes, and sort index to transmit information on both selected and unselected time slots. At the receiver, the variance of noise was reduced and the system’s error performance was improved by the use of denoising techniques. Formulas for bit error rate (BER) were derived for additive white Gaussian noise channels and multipath Rayleigh fading channels. Simulation results demonstrate that, compared to similar chaotic keying systems, the proposed system achieves higher data rates and superior error performance. |
