Distributed Wideband Sensing-based Architecture for Unlicensed Massive IoT Communications
Ghaith Hattab, Danijela Cabric
Providing Internet connectivity to a massive number of Internet-of-things (IoT) objects over the unlicensed spectrum requires: (i) identifying a very large number of narrowband cha…
Distributed Wideband Spatio-Spectral Sensing for Unlicensed Massive IoT Communications
Ghaith Hattab, Danijela Cabric
In this paper, we propose a dynamic spectrum sensing-based architecture to provide connectivity for a massive number of Internet-of-things (IoT) objects over the unlicensed spectru…
Performance Analysis of Uplink Cellular IoT Using Different Deployments of Data Aggregators
Ghaith Hattab, Danijela Cabric
Data aggregation is an effective solution to enable cellular support of Internet-of-things (IoT) communications. Indeed, it helps alleviate channel congestion, reduce the communica…
Tracking Sparse mmWave Channel under Time Varying Multipath Scatterers
Veljko Boljanovic, Han Yan, Danijela Cabric
Due to severe signal attenuation at millimeter-wave (mmWave) frequencies large antenna arrays are required at both base station and user equipment to achieve necessary beamfoming g…
Spectrum Sharing Protocols based on Ultra-Narrowband Communications for Unlicensed Massive IoT
Ghaith Hattab, Danijela Cabric
Ultra-narrowband (UNB) communications is an emerging paradigm that tackles two challenges to realizing massive Internet-of-things (IoT) connectivity over the unlicensed spectrum: t…
Deep Learning Based Transmitter Identification using Power Amplifier Nonlinearity
Samer S. Hanna, Danijela Cabric
The imperfections in the RF frontend of different transmitters can be used to distinguish them. This process is called transmitter identification using RF fingerprints. The nonline…
