Adaptive OFDM-IM for enhancing physical layer security and spectral efficiency of future wireless networks
(Hindawi Limited, 2018)
In this paper, we propose algorithms for enhancing physical layer security and spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) with Index Modulation (IM) systems. Particularly, different activation ...
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 ...
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 ...
Spatial and angular resolution enhancement of light fields using convolutional neural networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2018)
Light field imaging extends the traditional photography by capturing both spatial and angular distribution of light, which enables new capabilities, including post-capture refocusing, post-capture aperture control, and ...
Reducing demand signal variability via a quantitative fuzzy grey regression approach
(Strojarski Facultet, 2018)
The total system performance of dynamic and complex supply chain networks depends mainly on accurate demand signal estimation as incorporated with an appropriate decision-making process. Due to the field of activity and ...
