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…
