In the differential chaos shift keying (DCSK) system, half of the symbol period is used to
transmit the reference signal, resulting in the poor energy efficiency. The existing DCSK …

Among the various modulation schemes proposed for chaos-based digital communications,
chaos-shift keying (CSK) and differential chaos-shift keying (DCSK) have been most …

The bit error rate (BER) performance of chaos shift keying is improved for an additive white
Gaussian noise channel by applying a trimming operation to the Chebyshev polynomial …

Chaotic modulation has attracted much attention in the past two decades for low-power and
low-cost wireless communication applications due to its excellent anti-fading capability. In …

In this paper, noise reduction differential chaos shift keying (NR-DCSK)-based multiple-input–
multiple-output (MIMO) chaotic communication system is proposed. We consider a …
