Heuristic inspired precoding for millimeter-wave MIMO systems with lens antenna subarrays
(Institute of Electrical and Electronics Engineers Inc., 2022)A traditional array (TA) multiple-input multiple-output (MIMO) architecture in mmWave with hybrid beamforming suffers from high power consumption and hardware overhead. Therefore, a lens antenna subarray (LAS)-MIMO ... -
Secure key exchange and transmission design using artificial noise ınjection in OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2022)Orthogonal frequency division multiplexing (OFDM) is such a vital waveform scheme that is utilized in fifth-generation (5G) communication systems as well as the previous one. Since the usage scenarios of 5G are quite wide, ... -
Channel-dependent code allocation for downlink MC-CDMA system aided physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2022)Spreading codes are the core of the spread spectrum transmission. In this paper, a novel channel-dependent code allocation procedure for enhancing security in multi-carrier code division multiple access (MC-CDMA) system ... -
Dynamic-structure resource block allocation based scheduling for 5G systems
(Institute of Electrical and Electronics Engineers Inc., 2022)We propose an efficient radio resource scheduling (RRS) approach based on the existing dynamic resource block structure (D-RBS). The proposed RRS is more responsive to variations in traffic demand. More specifically, ... -
On the performance of handover mechanisms for non-terrestrial networks
(Institute of Electrical and Electronics Engineers Inc., 2022)Next-generation wireless networks require massive connectivity and ubiquitous coverage, for which non-terrestrial networks (NTNs) are a promising enabler. However, NTNs, especially non-geostationary satellites bring about ... -
