Secure spatial multiple access using directional modulation
(IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)
In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
Cognitive security of wireless communication systems in the physical layer
(Wiley-Hindawi, 2017)
While the wireless communication systems provide the means of connectivity nearly everywhere and all the time, communication security requires more attention. Even though current efforts provide solutions to specific ...
Flexible multi-numerology systems for 5G new radio
(River Publishers, 2018)
The physical layer of 5G cellular communications systems is designed to achieve better flexibility in an effort to support diverse services and user requirements. Orthogonal frequency division multiplexing (OFDM) waveform ...
A secure downlink NOMA scheme against unknown internal eavesdroppers
(IEEE-Institute of Electrical and Electronics Engineers Inc., 2021)
Enhancing security level against potential internal eavesdroppers in Non-Orthogonal Multiple Access (NOMA) has been reported as a serious challenge. In this letter, a novel secure NOMA scheme based on physical-layer security ...
Using OMP and SD algorithms together in mm-Wave mMIMO channel estimation
(Springer London Ltd, 2022)
Lens antenna array is considered as an effective beam selection mechanism in millimeter wave massive multiple input multiple output systems. Efficient channel estimation (CE) algorithms are required to use the advantage ...
Reducing precoder/channel mismatch and enhancing secrecy in practical MIMO systems using artificial signals
(IEEE - Institute of Electrical and Electronics Engineers, Inc, 2020)
Practical multiple-input-multiple-output (MIMO) systems depend on a predefined set of precoders to provide spatial multiplexing gain. This limitation on the flexibility of the precoders affects the overall performance. ...
Secure orthogonal transform division multiplexing (OTDM) waveform for 5G and beyond
(IEEE-Inst Electrical Electronics Engineers Inc, 2017)
In this letter, a secure waveform design for future 5G wireless system is proposed. The developed waveform referred to as secure orthogonal transform division multiplexing (OTDM) waveform, is designed to diagonalize the ...
Resource allocation with partially overlapping filtered multitone in cognitive heterogeneous networks
(IEEE-Inst Electrical Electronics Engineers INC, 2016)
Partially overlapping tones have recently been offered as a new solution to reduce the other user interference in cognitive heterogeneous networks. By introducing intentional carrier frequency shift, the users can exploit ...
Classifications and applications of physical layer security techniques for confidentiality: A comprehensive survey
(IEEE-Inst Electrical Electronics Engineers Inc, 2019)
Physical layer security (PLS) has emerged as a new concept and powerful alternative that can complement and may even replace encryption-based approaches, which entail many hurdles and practical problems for future wireless ...
Reliability enhancement in multi-numerology-based 5G new radio using INI-aware scheduling
(Springeropen, 2019)
Multi-numerology waveform-based 5G new radio (NR) systems offer great flexibility for different requirements of users and services. However, there is a new type of problem that is defined as inter-numerology interference ...
