A Joint PHY and MAC Layer Design for Coded Random Access with Massive MIMO
Lorenzo Valentini, Marco Chiani, Enrico Paolini
Grant-free access schemes are candidates to support future massive multiple access applications owing to their capability to reduce control signaling and latency. As a promising cl…
Irregular Repetition Slotted ALOHA in an Information-Theoretic Setting
Enrico Paolini, Lorenzo Valentini, Velio Tralli +1
An information-theoretic approach to irregular repetition slotted ALOHA (IRSA) is proposed. In contrast with previous works, in which IRSA analysis is conducted only based on quant…
Two-Leg Deep Space Relay Architectures: Performance, Challenges, and Perspectives
Dario Modenini, Alfredo Locarini, Lorenzo Valentini +6
In this paper, architectures for interplanetary communications that feature the use of a data relay are investigated. In the considered "two-leg" architecture, a spacecraft orbitin…
Impact of Interference Subtraction on Grant-Free Multiple Access with Massive MIMO
Lorenzo Valentini, Alberto Faedi, Marco Chiani +1
The design of highly scalable multiple access schemes is a main challenge in the evolution towards future massive machine-type communications, where reliability and latency constra…
