Optical Index-Coded Space Shift Keying (IC/SSK)
(Institute of Electrical and Electronics Engineers Inc, 2021)
In this letter, a new channel coding technique is proposed for optical spatial shift keying (SSK)-based visible light communications (VLC) systems by introducing redundancy in the spatial domain. The information is encoded ...
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 ...
Relay-Aided Secure Broadcasting for Visible Light Communications
(IEEE-Inst Electrical Electronics Engineers Inc, 2019)
A visible light communication broadcast channel is considered, in which a transmitter luminaire communicates with two legitimate receivers in the presence of an external eavesdropper. A number of trusted cooperative ...
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
(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 ...
