In this study, we investigate a non-orthogonal multiple access (NOMA)-assisted dual-hop underwater wireless optical communication-radio frequency (UWOC-RF) network. Specifically, an source forwards NOMA signal to marine relay, which first deploys either the heterodyne detection or intensity modulation direct process received signal, and then encodes re-transmits superimposed two terrestrial destinations. Assuming UWOC channel is subject unified mixture Exponential-Generalized Gamma (mEGG)...
With the expansion of human activities into ocean, there is an urgent need for information transmission technology with higher data rates and more security. On other hand, satellite communication plays important role in maritime area, but also vulnerable to eavesdropping because its broadcast nature. Therefore, this study, physical-layer security a hybrid underwater wireless optical (UWOC) system considered. Specifically, source first broadcasts overwater relay via RF link, then converts...
In this paper, we investigate the performance for a mixed dual-hop free space optical-underwater wireless optical communication (FSO-UWOC) system, in which source transmits information to destination through multi-aperture relay. addition, selection combining and transmitting aperture select- ion protocols are adopted at relay process received transmitted signals. Considering two different types of detection techniques, decode-and-forward scheme, analytical expressions average bit error rate...
In this article, we evaluate the outage performance for a wireless-powered relaying radio frequency-underwater wireless optical communication (RF-UWOC) network with an amplify-and-forward protocol. Specifically, source transmits RF signal to power-constrained offshore relay, which first adopts power-splitting protocol harmonize information encoding and energy collecting of received then converts it one utilizes harvested broadcast destination. Assuming UWOC links undergo Nakagami-m...
