Lattice-Based Analog Mappings for Low-Latency Wireless Sensor Networks
Pedro Suárez-Casal, Óscar Fresnedo, Darian Pérez-Adán +1
We consider the transmission of spatially correlated analog information in a wireless sensor network (WSN) through fading single-input and multiple-output (SIMO) multiple access ch…
A Rank-Constrained Coordinate Ascent Approach to Hybrid Precoding for the Downlink of Wideband Massive (MIMO) Systems
José P. González-Coma, Óscar Fresnedo, Luis Castedo
An innovative approach to hybrid analog-digital precoding for the downlink of wideband massive MIMO systems is developed. The proposed solution, termed Rank-Constrained Coordinate…
Deep Contextual Bandit and Reinforcement Learning for IRS-Assisted MU-MIMO Systems
Dariel Pereira-Ruisánchez, Óscar Fresnedo, Darian Pérez-Adán +1
The combination of multiple-input multiple-output (MIMO) systems and intelligent reflecting surfaces (IRSs) is foreseen as a critical enabler of beyond 5G (B5G) and 6G. In this wor…
Transmission of Spatio-Temporal Correlated Sources Over Fading Multiple Access Channels With DQLC Mappings
O. Fresnedo, P. Suárez-Casal, L. Castedo
The design of zero-delay Joint Source-Channel Coding (JSCC) schemes for the transmission of correlated information over fading Multiple Access Channels (MACs) is an interesting pro…
Design of Linear Precoders for Correlated Sources in MIMO Multiple Access Channels
P. Suárez-Casal, J. P. González-Coma, O. Fresnedo +1
This work focuses on distributed linear precoding when users transmit correlated information over a fading Multiple-Input and Multiple-Output Multiple Access Channel. Precoders are…
Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems
J. P. González-Coma, J. Rodríguez-Fernández, N. González-Prelcic +2
Configuring the hybrid precoders and combiners in a millimeter wave (mmWave) multiuser (MU) multiple-input multiple-output (MIMO) system is challenging in frequency selective chann…
