Beam and User Selection Technique in Millimeter Wave Communications
Cumali, I.; Ozbek, B.; Pyattaev, A. (Institute of Electrical and Electronics Engineers Inc., 2020)Millimeter wave (mmWave) communication is a promising technology to fulfill the requirements of future wireless networks. It provides very large spectrum and a large number of antennas can be practicable due to the small ... -
Compressive Sensing based Low Complexity User Selection for Massive MIMO Systems
Ytlmaz, S.S.; Ozbek, B. (Institute of Electrical and Electronics Engineers Inc., 2020)Massive Multiple-input Multiple-output (MIMO) is widely considered as a key enabler of the next-generation networks. In these systems, user selection strategies are important to achieve spatial diversity and maximize ... -
Effect of mobile relays on the OFDMA-based cellular network performance [Gezgin rölelerin DFBÇE tabanli hücresel ?g performansina etkisi]
Basturk, I.; Ozbek, B. (IEEE Computer Society, 2014)OFDMA-based mobile relay enhanced cellular networks which have lower infrastructure cost and larger coverage areas are important technologies for the next generation communication systems since they allow to communicate ... -
Fair resource allocation for multi-user MISO-OFDMA systems [Çoklu kullanicili çgtç-dfbçe si?stemleri i?çi?n adi?l kaynak paylaşimi]
Başturk, I.; Ozbek, B. (2011)In this study, the user selection at the base station and resource allocation algorithms are presented for multiuser multipleinput single-output orthogonal frequency division multiple access (MU-MISO OFDMA) systems when ... -
Hybrid beamforming for secure multiuser mmWave MIMO communications
Erdogan, O.; Ozbek, B.; Busari, S.A.; Gonzalez, J. (Institute of Electrical and Electronics Engineers Inc., 2020)Secure communication is critical in wireless networks as the networks are prone to eavesdropping from unintended nodes. To address this challenge, physical layer security (PLS) is being employed to combat information ...
