Flexible numerology in 5G NR: Interference quantification and proper selection depending on the scenario
(Hindawi Ltd, 2021)
The 3rd Generation Partnership Project (3GPP) adopted cyclic prefix OFDM (CP-OFDM) for both uplink and downlink communications (although DFT-s-OFDM is also allowed in the uplink) in 5G New Radio (NR) Release 15. However, ...
Efficient spectrum occupancy prediction exploiting multidimensional correlations through composite 2D-LSTM models
(MDPI, 2021)
In cognitive radio systems, identifying spectrum opportunities is fundamental to efficiently use the spectrum. Spectrum occupancy prediction is a convenient way of revealing opportunities based on previous occupancies. ...
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 ...
Inter-numerology interference in OFDM-IM systems
(Wiley, 2021)
In 5G and beyond communication systems, distinct numerologies can coexist to serve diverse requirements for users and applications. However, the inter-numerology interference (INI) is a main challenge that significantly ...
Wireless communication, sensing, and REM: A security perspective
(Institute of Electrical and Electronics Engineers Inc., 2021)
The diverse requirements of next-generation communication systems necessitate awareness, flexibility, and intelligence as essential building blocks of future wireless networks. The awareness can be obtained from the radio ...
Wireless sensing – enabler of future wireless technologies
(Türkiye Klinikleri, 2021)
With the completion of the 5G standardization efforts, the wireless communication world has now turned to the road ahead, the future wireless communication visions. One common vision is that future networks will be flexible, ...
