Energy-Efficient Cell-Free Massive MIMO with Wireless Fronthaul
Ozan Alp Topal, Özlem Tuğfe Demir, Emil Björnson +1
Cell-free massive MIMO improves the fairness among the user equipments (UEs) in the network by distributing many cooperating access points (APs) around the region while connecting…
Communicate or Sense? AP Mode Selection in mmWave Cell-Free Massive MIMO-ISAC
Weixian Yan, Ozan Alp Topal, Zinat Behdad +2
Integrated sensing and communication (ISAC) is a promising technology for future mobile networks, enabling sensing applications to be performed by existing communication networks,…
Multi-Target Integrated Sensing and Communications in Massive MIMO Systems
Ozan Alp Topal, Özlem Tuğfe Demir, Emil Björnson +1
Integrated sensing and communications (ISAC) allows networks to perform sensing alongside data transmission. While most ISAC studies focus on single-target, multi-user scenarios, m…
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…
