WebAug 14, 2024 · The DCSK scheme is employed for modulating and demodulating legitimate signals. In addition, the logistic map is exploited for generating chaotic sequences. A mathematical representation of the map is given by [ 1 ] (1) where E [ xk] = 0, , and . For the modulation process, each bit duration is divided into two equal time slots. WebIn this study, we investigate an enhanced architecture of multicarrier differential chaos-shift keying (MC-DCSK) scheme using quadrature modulation (QM), namely QMC-DCSK. The use of quadrature modulation aims at doubling the data rate over a defined bandwidth and hence improve bandwidth efficiency of the system.
