Orthogonality Analysis in LoRa Uplink Satellite Communications Affected by Doppler Effect
Jikang Deng, Fatma Benkhelifa, Mohamed-Slim Alouini
This paper provides, for the first time, analytical expressions for the Long-Range (LoRa) waveform and cross-correlation in both continuous and discrete time domains under the Dopp…
Power Source Allocation for RIS-aided Integrating Sensing, Communication, and Power Transfer Systems Based on NOMA
Yue Xiu, Yang Zhao, Chenfei Xie +5
This paper proposes a novel communication system framework based on a reconfigurable intelligent surface (RIS)-aided integrated sensing, communication, and power transmission (ISCP…
Resource Allocation for NOMA-based LPWA Networks Powered by Energy Harvesting
Fatma Benkhelifa, Julie A. McCann
In this paper, we explore perpetual, scalable, Low-powered Wide-area networks (LPWA). Specifically we focus on the uplink transmissions of non-orthogonal multiple access (NOMA)-bas…
Spatiotemporal Modelling of Multi-Gateway LoRa Networks with Imperfect SF Orthogonality
Yathreb Bouazizi, Fatma Benkhelifa, Julie McCann
Meticulous modelling and performance analysis of Low-Power Wide-Area (LPWA) networks are essential for large scale dense Internet-of-Things (IoT) deployments. As Long Range (LoRa)…
Resource Allocation for Non-Orthogonal Multiple Access (NOMA) Enabled LPWA Networks
Kaihan Li, Fatma Benkhelifa, Julie McCann
In this paper, we investigate the resource allocation for uplink non-orthogonal multiple access (NOMA) enabled low-power wide-area (LPWA) networks to support the massive connectivi…
Minimum Throughput Maximization in LoRa Networks Powered by Ambient Energy Harvesting
Fatma Benkhelifa, Zhijin Qin, Julie McCann
In this paper, we investigate the uplink transmissions in low-power wide-area networks (LPWAN) where the users are self-powered by the energy harvested from the ambient environment…
