Optimizing Reconfigurable Intelligent Surfaces for Small Data Packets: A Subarray Approach
Anders Enqvist, Özlem Tuğfe Demir, Cicek Cavdar +1
In this paper, we examine the energy consumption of a user equipment (UE) when it transmits a finite-sized data packet. The receiving base station (BS) controls a reconfigurable in…
mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces
Zhenyu Li, Ozan Alp Topal, Özlem Tuğfe Demir +2
In this work, we consider the deployment of reconfigurable intelligent surfaces (RISs) to extend the coverage of a millimeter-wave (mmWave) network in indoor dense spaces. We first…
Power Allocation for Joint Communication and Sensing in Cell-Free Massive MIMO
Zinat Behdad, Özlem Tuğfe Demir, Ki Won Sung +2
This paper studies a joint communication and sensing (JCAS) system with downlink communication and multi-static sensing for single-target detection in a cloud radio access network…
Channel Estimation under Hardware Impairments: Bayesian Methods versus Deep Learning
Özlem Tugfe Demir, Emil Björnson
This paper considers the impact of general hardware impairments in a multiple-antenna base station and user equipments on the uplink performance. First, the effective channels are…
