Fundamentals of Energy-Efficient Hardware Configurations for Wireless Links with Sleep Modes
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 (PC) model that captures the passive…
Exploiting Pilot Contamination to Improve UL Sum Rate under Maximum Ratio Combining
Emanuel Wennemo, Ki Won Sung, Emil Björnson
In this work, we show that pilot contamination can be exploited to jointly increase the uplink sum rate and reduce pilot overhead. By leveraging the effect of pilot contamination o…
Mask-Compliant Clipping-Aware Precoding for Multi-User MIMO-OFDM Systems
Navid Reyhanian, Parisa Ramezani, Emil Björnson
Orthogonal frequency-division multiplexing (OFDM) is widely adopted in frequency-selective channels for its ability to simplify equalization, yet it also causes large signal peaks,…
Joint Access and Fronthaul Resource Allocation for Cell-Free Massive MIMO with Wireless Fronthaul
Ozan Alp Topal, Özlem Tuğfe Demir, Emil Björnson +1
Wireless fronthaul is a key enabler of flexible and scalable cell-free massive MIMO systems, but its limited capacity poses significant challenges for maintaining high and uniform…
Performance Analysis for ISAC Systems with 1-bit DACs
Murat Babek Salman, Özlem Tugfe Demir, Emil Björnson
Low-resolution quantization constrains the maximum achievable gains of multiple-input multiple-output (MIMO) systems. While the adverse effects and mitigation strategies have been…
Energy-Efficient Dual-Band Communication: How to Allocate Traffic to Sub-THz Carriers?
Anders Enqvist, Emil Björnson, Cicek Cavdar
As 6G wireless networks transition toward sub-Terahertz (sub-THz) frequencies to satisfy extreme capacity demands, managing the trade-off between massive bandwidth and power consum…
