A distributed user-cell association for spectral and energy efficiency tradeoff in massive MIMO UDHNs
Çetinkaya, Şinasi; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers, 2019)Massive MIMO enabled ultra-dense heterogeneous networks (UDHNs) have been considered as the indispensable and emerging approach to meet the demand on growing data traffic for next generation networks. Although deployment ... -
Energy and spectral efficiency tradeoff in NOMA: Multi-objective evolutionary approaches
Çetinkaya, Şinasi; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2020)Non-orthogonal multiple access (NOMA) deployment in future wireless networks has been recently considered a promising radio access technology to enhance spectral efficiency (SE). However, gain in SE comes always with the ... -
Heuristic inspired precoding for millimeter-wave MIMO systems with lens antenna subarrays
Çetinkaya, Şinasi; Afeef, Liza; Mumcu, Gökhan; Arslan, Hüseyin (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 ...
