D2D-aided LoRaWAN LR-FHSS in Direct-to-Satellite IoT Networks
Alireza Maleki, Ha H. Nguyen, Ebrahim Bedeer +1
In this paper, we present a device-to-device (D2D) transmission scheme for aiding long-range frequency hopping spread spectrum (LR-FHSS) LoRaWAN protocol with application in direct…
Performance Improvement of LoRa Modulation with Signal Combining and Semi-Coherent Detection
The Khai Nguyen, Ha H. Nguyen, Ebrahim Bedeer
In this paper, we investigate performance improvements of low-power long-range (LoRa) modulation when a gateway is equipped with multiple antennas. We derive the optimal decision r…
Polar Coded Faster-than-Nyquist (FTN) Signaling with Symbol-by-Symbol Detection
Abdulsamet Caglan, Adem Cicek, Enver Cavus +2
Reduced complexity faster-than-Nyquist (FTN) signaling systems are gaining increased attention as they provide improved bandwidth utilization for an acceptable level of detection c…
Low-Complexity Detection for Faster-than-Nyquist Signaling based on Probabilistic Data Association
Michel Kulhandjian, Ebrahim Bedeer, Hovannes Kulhandjian +2
In this paper, we investigate the sequence estimation problem of faster-than-Nyquist (FTN) signaling as a promising approach for increasing spectral efficiency (SE) in future commu…
Energy Efficiency Maximization of Self-Sustained Wireless Body Area Sensor Networks
Osama Amjad, Ebrahim Bedeer, Salama Ikki
Electronic health monitoring is one of the major applications of wireless body area networks (WBANs) that helps with early detection of any abnormal physiological symptoms. In this…
