In this study, the response of a nonlinear laser medium is experimentally studied. In the study, a hybrid version of the input layer that multiplies optically and accumulates electrically is compared with a wholly optical version that multiplies and

In this paper, a chaotic secure communication system based on single feedback phase modulation is designed, in which phase modulation of feedback light is carried out by using random square wave as communication key, and chaotic light with wide spect

In this paper, we present an efficient amplitude shift keying (ASK)-aided orthogonal chaotic vector PSK (ASK-OCVPSK) non-coherent modulation scheme with considerations of different quality of service (QoS) demands. In our ASK-OCVPSK design, the refer

Visible light communication (VLC) systems have relatively higher security compared with traditional radio-frequency (RF) channel thanks to line-of-sight (LOS) propagation. However, due to the broadcasting property of optical channels, VLC systems may

A new non-coherent chaotic modulation technique based on adaptive decision threshold is proposed for the UltraWideBand (UWB) Direct Chaotic Communication (DCC) technology. The principal advantages of the proposed technique are: (1) Removing the thr

We propose a trellis-coded chaotic modulation scheme employing the symbolic dynamics generated by three-dimensional chaotic flows. The continuous chaotic trajectories are discretized using a labeled partition of a Poincare section. The discrete dynam
