Bidirectional Optical Spatial Modulation for Mobile Users: Toward a Practical Design for LiFi Systems
Soltani M.D.; Arfaoui M.A.; Tavakkolnia I.; Ghrayeb A.; Safari M.; Assi C.M.; Hasna M.O.; Haas H.... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Among the challenges of realizing the full potential of light-fidelity (LiFi) cellular networks are user mobility, random device orientation, and blockage. In this paper, we study the impact of those challenges on the ... -
Outage performance of multi-hop hybrid FSO/RF communication systems
Kazemi H.; Uysal M.; Touati F.; Haas H. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ... -
Precoding-Aided Spatial Modulation for the Wiretap Channel with Relay Selection and Cooperative Jamming
Bouida Z.; Stavridis A.; Ghrayeb A.; Haas H.; Hasna , Mazen; Ibnkahla M.... more authors ... less authors ( Hindawi Limited , 2018 , Article)We propose in this paper a physical-layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ...
