DOI: 10.1109/jcn.2018.000042
Abstract: This paper proposes a multi-carrier differential chaos-shift keying (MC-DCSK) system using repeated spreading sequence (RSS), namely RSS-MC-DCSK, for chaos-based wireless communications. In the proposed system, instead of transmitting the chaotic spreading sequence on a predefined… read more here.
