An Implementation of the Optimal Scheme for Energy Efficient Bus Encoding
Lorenzo Valentini, Marco Chiani
In computer system buses, most of the energy is spent to change the voltage of each line from high to low or vice versa. Bus encoding schemes aim to improve energy efficiency by li…
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…
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…
Optimum Detection of Defective Elements in Non-Adaptive Group Testing
Gianluigi Liva, Enrico Paolini, Marco Chiani
We explore the problem of deriving a posteriori probabilities of being defective for the members of a population in the non-adaptive group testing framework. Both noiseless and noi…
Limits on Sparse Data Acquisition: RIC Analysis of Finite Gaussian Matrices
Ahmed Elzanaty, Andrea Giorgetti, Marco Chiani
One of the key issues in the acquisition of sparse data by means of compressed sensing (CS) is the design of the measurement matrix. Gaussian matrices have been proven to be inform…
