Channel Estimation and Equalization for Alamouti SF-Coded OFDM-UWA Communications
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2021-02)
In this paper, a new channel estimation and equalization algorithm for underwater acoustic (UWA) communications is presented. The proposed algorithm is developed to meet the requirements of underwater time-varying sparse ...
Physical Layer Security for Multi-User MIMO Visible Light Communication Systems with Generalized Space Shift Keying
(Institute of Electrical and Electronics Engineers Inc., 2021)
We consider the physical layer security (PLS) of multi-user (MU) multiple-input-multiple-output visible light communication (VLC) systems with an eavesdropper (Eve) and propose a novel spatial constellation design technique ...
Physical-Layer Security With Optical Generalized Space Shift Keying
(Ieee-Inst Electrıcal Electronıcs Engıneers Inc, 2020)
Spatial modulation (SM) is a promising technique that reduces inter-channel interference while providing high power efficiency and detection simplicity. In order to ensure the secrecy of SM, precoding and friendly jamming ...
Signal Processing Techniques for 6G
(Springer, 2023)
6G networks have the burden to provide not only higher performance compared to 5G, but also to enable new service domains as well as to open the door over a new paradigm of mobile communication. This paper presents an ...
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 ...
3D indoor positioning with spatial modulation for visible light communications
(Elsevier, 2023)
In this paper, a novel three-dimensional (3D) indoor visible light positioning (VLP) algorithm is proposed based on the spatial modulation (SM) and its error performance assessed as compared to the conventional received ...
Next-Generation Multiple Access Based on NOMA With Power Level Modulation

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 ...
Physical-Layer Security in 6G Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2021)
The sixth generation (6G) of mobile network will be composed by different nodes, from macro-devices (satellite) to nano-devices (sensors inside the human body), providing a full connectivity fabric all around us. These ...
3D-printed actuator-based beam-steering approach for improved physical layer security in visible light communication
(Optica Publishing Group, 2022)
In this study, we present the design, manufacture, and implementation of a 3D-printed lens scanner-based beam steering for use in visible light communication (VLC) applications. The 5 cm x 5 cm scanner is designed for ...
Security and Reliability Performance of Noise-Loop Modulation: Theoretical Analysis and Experimentation
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)
Security is a crucial feature of current (5G) and even more for future (6G) communication networks. While the innate nature of the wireless channel is an issue for guaranteeing security, its physical characteristics can ...
