Optimal Fairness Scheduling for Coded Caching in Multi-AP Multi-antenna WLAN
Kagan Akcay, MohammadJavad Salehi, Antti Tölli +1
Coded caching (CC) schemes exploit the cumulative cache memory of network users, outperforming traditional uncoded schemes where cache contents are only used locally. Interestingly…
Low-complexity Linear Multicast Beamforming for Cache-aided MIMO Communications
Mohammad NaseriTehrani, MohammadJavad Salehi, Antti Tölli
A practical and scalable multicast beamformer design in multi-input multi-output~(MIMO) coded caching~(CC) systems is introduced in this paper. The proposed approach allows multica…
Enhanced Uplink Data Detection for Massive MIMO with 1-Bit ADCs: Analysis and Joint Detection
Amin Radbord, Italo Atzeni, Antti Tolli
We present a new analytical framework on the uplink data detection for massive multiple-input multiple-output systems with 1-bit analog-to-digital converters (ADCs). We first chara…
Pilot-Based Uplink Power Control in Single-UE Massive MIMO Systems With 1-Bit ADCs
