Deep-Learning-Aided Cross-Layer Resource Allocation of OFDMA/NOMA Video Communication Systems
IEEE Access, 2019 In previous study, deep learning and autoencoder have been applied for data detection of NOMA systems, rather than the resource allocation of OFDMA/NOMA systems.

Enhancing Wi-Fi 6 spectrum access control with a heuristic OFDMA back-off mechanism
Results in EngineeringThe IEEE 802.11ax standard, known as Wi-Fi 6, employs a centralized, multiuser, uplink Orthogonal Frequency Division Multiple Access (OFDMA)-based Random Access (UORA) mechanism to improve user efficiency and network capacity in dense environments. In Wi-

Subcarrier Allocation Techniques in OFDMA
International Journal of Innovative Technology and Exploring Engineering, 2019 Orthogonal Frequency Division several Access (OFDMA) is a access that is numerous where the regularity musical organization is divided in to range subcarriers and each individual is assigned a subset of this subcarriers to be used. Although t he OFDMA framework provides a mechanism for a person to distribute information throughout the pair of assigned ...
