On Time-of-Arrival Estimation in NB-IoT Systems
Sha Hu, Xuhong Li, Fredrik Rusek
We consider time-of-arrival (ToA) estimation of a first arrival-path for a device working in narrowband Internet-of-Things (NB-IoT) systems. Due to a limited 180 KHz bandwidth used…
User Assignment with Distributed Large Intelligent Surface (LIS) Systems
Sha Hu, Krishna Chitti, Fredrik Rusek +1
In this paper, we consider a wireless communication system where a large intelligent surface (LIS) is deployed comprising a number of small and distributed LIS-Units. Each LIS-Unit…
Sequential Channel Estimation in the Presence of Random Phase Noise in NB-IoT Systems
Fredrik Rusek, Sha Hu
We consider channel estimation (CE) in narrowband Internet-of-Things (NB-IoT) systems. Due to the fluctuations in phase within receiver and transmitter oscillators, and also the re…
The Potential of Using Large Antenna Arrays on Intelligent Surfaces
Sha Hu, Fredrik Rusek, Ove Edfors
In this paper, we consider capacities of single-antenna terminals communicating to large antenna arrays that are deployed on surfaces. That is, the entire surface is used as an int…
