Channel randomness-based adaptive cyclic prefix selection for secure OFDM system
Naderi, Sanaz; da Costa, Daniel Benevides; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)A novel method for cyclic prefix (CP) adaptation based on wireless channel randomness is proposed for orthogonal frequency-division multiplexing (OFDM) systems in urban areas. Especially, a quantization algorithm and an ... -
Efficient spectrum occupancy prediction exploiting multidimensional correlations through composite 2D-LSTM models
Aygül, Mehmet Ali; Nazzal, Mahmoud; Sağlam, Mehmet İzzet; da Costa, Daniel Benevides; Ateş, Hasan Fehmi; Arslan, Hüseyin (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. ... -
Joint random subcarrier selection and channel-based artificial signal design aided PLS
Naderi, Sanaz; da Costa, Daniel Benevides; Arslan, Hüseyin (IEEE - Institute of Electrical and Electronics Engineers, Inc., 2020)A novel method for providing physical layer security (PLS) depending on the randomness of wireless channel is proposed. Specifically, a channel-based joint random subcarrier selection and artificial signal design are ... -
User pairing and power allocation strategies for 3D VLC-NOMA systems
Janjua, Muhammad Bilal; da Costa, Daniel Benevides; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2020)In this letter, we propose two novel, yet efficient, user pairing schemes for non-orthogonal multiple access (NOMA) in 3D visible light communication (VLC). Our analysis is carried out assuming different heights for the ...
