Hybrid Decode-Forward & Amplify-Forward Relaying With Non-Orthogonal Multiple Access
IEEE Access, 2016 Cooperative communication has used to be a hot topic and it has been studied extensively in the past 10 years, but in recent years, it becomes less likely to find substantial innovation in this field as before.

Secrecy Performance Analysis of Relay Selection in Cooperative NOMA Systems
IEEE Access, 2019 This paper investigates the security performance of two relay selection schemes for cooperative non-orthogonal multiple access (NOMA) systems, where K randomly distributed relays are employed with either decode-and-forward (DF) or amplify-and-forward (AF)

Wireless Communications and Mobile Computing, 2020 In this paper, we evaluate the performance of a vehicle-to-vehicle (V2V) system where full-duplex relay (FDR) harvests the energy from source and uses decode-and-forward (DF) protocol to forward data from source to destination.

Switching-based cooperative decode-and-forward relaying for hybrid FSO/RF networks
IEEE\/OSA Journal of Optical Communications and Networking, 2019 In this paper, we propose a switching scheme for a hybrid free-space optical (FSO)/radio frequency (RF) system with a selective decode-and-forward (DF) relay network.

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates
Advanced Science, EarlyView.Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

On the Physical Layer Security of a Decode and Forward Based Mixed FSO/RF Co-Operative System [PDF]
IEEE Wireless Communications Letters, 2019 In this letter, the secrecy performance of a decode-and-forward (DF) principle based mixed free space optics (FSO) and radio frequency (RF) system is analyzed. The analysis is done from physical layer (PHY) security perspective.
