Low-Resolution Massive MIMO Under Hardware Power Consumption Constraints
Italo Atzeni, Antti Tölli, Giuseppe Durisi
We consider a fully digital massive multiple-input multiple-output architecture with low-resolution analog-to-digital/digital-to-analog converters (ADCs/DACs) at the base station (…
Latency-Aware Multi-antenna SWIPT System with Battery-Constrained Receivers
Dileep Kumar, Onel L. Alcaraz López, Satya Krishna Joshi +1
Power splitting (PS) based simultaneous wireless information and power transfer (SWIPT) is considered in a multi-user multiple-input-single-output broadcast scenario. Specifically,…
Low-Subpacketization Multi-Antenna Coded Caching for Dynamic Networks
MohammadJavad Salehi, Emanuele Parrinello, Hamidreza Bakhshzad Mahmoodi +1
Multi-antenna coded caching combines a global caching gain, proportional to the total cache size in the network, with an additional spatial multiplexing gain that stems from multip…
Joint Minimum DL-UL Rate Maximization for Cell-Free Massive MIMO
