Detecting Unauthorized Drones with Cell-Free Integrated Sensing and Communication
Xinyue Li, Zinat Behdad, Ozan Alp Topal +2
Integrated sensing and communication (ISAC) boosts network efficiency by using existing resources for diverse sensing applications. In this work, we propose a cell-free massive MIM…
Fundamentals of Energy-Efficient Wireless Links: Optimal Ratios and Scaling Behaviors
Anders Enqvist, Özlem Tuğfe Demir, Cicek Cavdar +1
In this paper, we examine the energy efficiency (EE) of a base station (BS) with multiple antennas. We use a state-of-the-art power consumption model, taking into account the passi…
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…
mmWave Communications for Indoor Dense Spaces: Ray-Tracing Based Channel Characterization and Performance Comparison
Ozan Alp Topal, Mustafa Ozger, Dominic Schupke +2
In this paper, the indoor dense space (IDS) channel at 28 GHz is characterized through extensive Ray-Tracing (RT) simulations. We consider IDS as a specific type of indoor environm…
Energy-Reliability Aware Link Optimization for Battery-Powered IoT Devices with Non-Ideal Power Amplifiers
Aamir Mahmood, M. M. Aftab Hossain, Cicek Cavdar +1
In this paper, we study cross-layer optimization of low-power wireless links for reliability-aware applications while considering both the constraints and the non-ideal characteris…
Performance Evaluation and Optimization of LPWA IoT Networks: A Stochastic Geometry Approach
Amin Azari, Cicek Cavdar
Leveraging grant-free radio access for enabling lowpower wide-area (LPWA) Internet of Things (IoT) connectivity has attracted lots of attention in recent years. Regarding lack of r…
