The Effect of Codebook Design on the Conventional SCMA System Performance
Kiracı, Furkan; Bardakçı, Emine; Sadi, Yalçın; Erküçük, Serhat (IEEE, 2020)In 4G systems, Orthogonal Frequency-Division Multiple Access (OFDMA) has been used conventionally for multiple access purposes. This technique has low spectral efficiency since it allocates the resources orthogonally to ... -
Machine type communications: key drivers and enablers towards the 6G era
Mahmood, Nurul Huda; Boecker, Stefan; Moerman, Ingrid; Lopez, Onel A.; Munari, Andrea; Mikhaylov, Konstantin; Clazzer, Federico; Bartz, Hannes; Park, Ok-Sun; Mercier, Eric; Saidi, Selma; Osorio, Diana Moya; Jantti, Riku; Pragada, Ravikumar; Annanpera, Elina; Ma, Yihua; Wietfeld, Christian; Andraud, Martin; Liva, Gianluigi; Chen, Yan; Garro, Eduardo; Burkhardt, Frank; Liu, Chen-Feng; Alves, Hirley; Sadi, Yalçın; Kelanti, Markus; Dore, Jean-Baptiste; Kim, Eunah; Shin, JaeSheung; Park, Gi-Yoon; Kim, Seok-Ki; Yoon, Chanho; Anwar, Khoirul; Seppanen, Pertti (SPRINGER, 2021)The recently introduced 5G New Radio is the first wireless standard natively designed to support critical and massive machine type communications (MTC). However, it is already becoming evident that some of the more demanding ... -
QoS-Constrained Semi-Persistent Scheduling of Machine-Type Communications in Cellular Networks
Karadağ, Göksu; Gül, Recep; Sadi, Yalçın; Ergen, Sinem Coleri (IEEE, 2019)The dramatic growth of machine-to-machine (M2M) communication in cellular networks brings the challenge of satisfying the quality of service (QoS) requirements of a large number of M2M devices with limited radio resources. ... -
Scheduling and Relay Selection for Full-Duplex Wireless Powered Cooperative Communication Networks
Iqbal, Muhammad Shahid; Syed, Kazmi Abbas Adil; Coleri, Sinem; Sadi, Yalçın (Institute of Electrical and Electronics Engineers Inc., 2020)In this manuscript, we consider a full-duplex wireless powered cooperative communication system where the users communicate with a hybrid access point through relays. We formulate an optimization problem with the objective ...
