Identification of the number of wireless channel taps using deep neural networks
Jaradat, Ahmad M.; Elgammal, Khaled Walid; Özdemir, Mehmet Kemal; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2021)In wireless communication systems, identifying the number of channel taps offers an enhanced estimation of the channel impulse response (CIR). In this work, efficient identification of the number of wireless channel taps ... -
Low-complexity deep learning-based beamforming in MISO systems
Thet, Nann Win Moe; Elgammal, Khaled Walid; Ateş, Hasan Fehmi; Özdemir, Mehmet Kemal (Institute of Electrical and Electronics Engineers Inc., 2021)This study proposes a low-complexity deep learning-based beamforming neural network (BFNN) for massive multiple-input single-output (MISO) systems. We adopt an unsupervised learning-based convolutional neural network (CNN) ... -
Signal of opportunity based TDOA positioning using analog TV signals
Elgammal, Khaled Walid; Turan, Berke Can; Bedir, Oğuz; Çelebi, Hasari; Özdemir, Mehmet Kemal (IEEE Computer Society, 2023)The ability to self-localize is an essential requirement for many systems. Mostly, this is accomplished by using a Global Positioning System (GPS) receiver. However, in some situations, the GPS receiver is disabled by ... -
Software implementation of key transceiver algorithms for an in-band full-duplex DVB-S2-based satellite communication system
Elgammal, Khaled Walid (İstanbul Medipol Üniversitesi Fen Bilimleri Enstitüsü, 2021)Nowadays, the demand for satellite bandwidth is boosted driven by the introduction of new areas of applications such as 5G-satellite integration and the internet of things. In-Band Full-Duplex communications, where a ...
