Flexible LED Index Modulation for MIMO Optical Wireless Communications
(Institute of Electrical and Electronics Engineers Inc., 2020)
The limited bandwidth of optical wireless communication (OWC) front-end devices motivates the use of multipleinput- multiple-output (MIMO) techniques to enhance data rates. It is known that very high multiplexing gains can ...
Spatial Constellation Design Based Generalized Space Shift Keying for Physical Layer Security of Multi-User MIMO Communication Systems
(Institute of Electrical and Electronics Engineers Inc., 2021)
We propose a novel spatial constellation design (SCD) method with generalized space shift keying (GSSK-SCD) signaling for physical layer security (PLS) in multi-user (MU) multiple-input multiple-output (MIMO) communication ...
Spatial Modulation Aided Physical Layer Security for NOMA-VLC Systems
(IEEE-Inst Electrical Electronics Engineers Inc, 2023)
We consider the physical layer security (PLS) problem in multi-user non-orthogonal multiple access (NOMA) enabled multiple-input multiple-output (MIMO) visible light communication systems intercepted by a passive eavesdropper ...
Next-Generation Multiple Access Based on NOMA With Power Level Modulation
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)
To cope with the explosive traffic growth expected in next-generation wireless networks, it is necessary to design next-generation multiple access techniques that can provide higher spectral efficiency as well as larger-scale ...
