Interference Cancellation Algorithms for Grant-Free Multiple Access with Massive MIMO
Lorenzo Valentini, Marco Chiani, Enrico Paolini
In next generation Internet-of-Things, the overhead introduced by grant-based multiple access protocols may engulf the access network as a consequence of the unprecedented number o…
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…
Analysis of Pointing Loss Effects in Deep Space Optical Links
Lorenzo Valentini, Alberto Faedi, Enrico Paolini +1
Owing to the extremely narrow beams, a main issue in optical deep space communications is represented by miss-pointing errors, which may severely degrade the system performance and…
On Oversampling-Based Signal Detection
Andrea Mariani, Andrea Giorgetti, Marco Chiani
The availability of inexpensive devices allows nowadays to implement cognitive radio functionalities in large-scale networks such as the internet-of-things and future mobile cellul…
