Statistical analysis of OFDMA assignments
2008 IEEE International Symposium on Wireless Communication Systems, 2008 In this paper we investigate statistical properties of IP optimal subcarrier assignments in the down-link of an OFDMA cell. Essentially, we show that such subcarrier assignments do have ?hidden? statistical properties which can be exploited to design an extremely simple assignment strategy.

Analysis of Low Probability of Detection Capability for Chaotic Standard Map-Based FH-OFDMA System
Applied Sciences, 2021 A frequency hopping orthogonal frequency division multiple access (FH-OFDMA) can provide low probability of detection (LPD) and anti-jamming capabilities to users against adversary detectors. To obtain an extreme LPD capability that cannot be provided by

Buffer sharing on an OFDMA downlink
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010 In this work we consider the allocation of buffer space to data streams sharing a common high-speed wireless transmitter. As an example, we focus on an OFDMA-based downlink system scenario. Scheduling for maximum throughput has been extensively studied in the literature.

Dimensioning of 5G Networks by Using Stochastic Geometry
International Journal of Information and Communication Technology Research, 2021 In this paper, we propose an analytical model for dimensioning of Orthogonal Frequency Division Multiple Access (OFDMA) systems in 5G networks by considering Internet of Thing (IoT) application using stochastic geometry.

Generalized Network-Coded Cooperation in OFDMA Communications
IEEE Access, 2018 Cooperative communication is a well-established technique to obtain diversity and consequently combat the fading inherent to the wireless channel. In a recent work, network-coded cooperation (NCC) along with graph theory-aided subcarrier allocation was ...
