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…
Multi-level Design for Multiple-Symbol Non-Coherent Unitary Constellations for Massive SIMO Systems
Son T. Duong, Ha H. Nguyen, Ebrahim Bedeer
This paper investigates non-coherent detection of single-input multiple-output (SIMO) systems over block Rayleigh fading channels. Using the Kullback-Leibler divergence as the desi…
Coordinate Interleaved Faster-than-Nyquist Signaling
Adem Cicek, Enver Cavus, Ebrahim Bedeer +2
Faster-than-Nyquist (FTN) signaling is an attractive transmission technique which accelerates data symbols beyond the Nyquist rate to improve the spectral efficiency; however, at t…
Deep Learning-based List Sphere Decoding for Faster-than-Nyquist (FTN) Signaling Detection
Sina Abbasi, Ebrahim Bedeer
Faster-than-Nyquist (FTN) signaling is a candidate non-orthonormal transmission technique to improve the spectral efficiency (SE) of future communication systems. However, such imp…
