Modulating Retroreflector-Aided UAV-Based FSO/QKD Systems
Duy N. Luong, Duy-Tuan Dao, Cuong T. Nguyen +2
Unmanned aerial vehicles (UAVs)-based free-space optics (FSO)/quantum key distribution (QKD) systems require high-precision pointing mechanisms. This increases system complexity an…
Key Reconciliation with RC-LDPC/Error Estimation for Satellite-based FSO/QKD Systems
Cuong T. Nguyen, Hoang D. Le, Anshul Jaiswal +2
Satellite-based free-space optics (FSO) quantum key distribution (QKD) systems have recently attracted significant research interest due to their potential to enable globally secur…
Secure RSMA-based Visible Light Networks under Spatial Correlation
Hung K. Hoang, Chuyen T. Nguyen, Thang K. Nguyen +2
This paper investigates the secrecy sum rate (SSR) of rate-splitting multiple access (RSMA)-based visible light communication (VLC) systems considering internal eavesdropping, wher…
Multi-user Visible Light Communications with Probabilistic Constellation Shaping and Precoding
Thang K. Nguyen, Thanh V. Pham, Hoang D. Le +2
This paper proposes a joint design of probabilistic constellation shaping (PCS) and precoding to enhance the sum-rate performance of multi-user visible light communications (VLC) b…
Joint Design of Probabilistic Constellation Shaping and Precoding for Multi-user VLC Systems
Thang K. Nguyen, Thanh V. Pham, Hoang D. Le +2
This paper proposes a joint design of probabilistic constellation shaping (PCS) and precoding to enhance the sum-rate performance of multi-user visible light communications (VLC) b…
Q-learning-based Joint Design of Adaptive Modulation and Precoding for Physical Layer Security in Visible Light Communications
Duc M. T. Hoang, Thanh V. Pham, Anh T. Pham +1
There has been an increasing interest in physical layer security (PLS), which, compared with conventional cryptography, offers a unique approach to guaranteeing information confide…
