Deep Tech to Space: Space Data Centers and AI Revolution at the Edge
Jonas Weiss, Patricia Sagmeister, Gabriel Maiolini Capez +16
Dramatic cost reductions driven by private sector innovations have led to a rapid increase in the number of satellites in orbit and a corresponding surge in space-generated data. A…
Wideband Direct Satellite Uplink Enabled by Pilot-less Sparse Superposition Codes
Alberto G. Perotti, Branislav M. Popovic, Renaud-Alexandre Pitaval
Direct satellite uplink is severely constrained by limited link budgets, which hinder the exploitation of wideband resources, and ultimately limit the throughout. This paper presen…
Multi-Modal Concurrent Transmission
Majid Nasiri Khormuji, Alberto Giuseppe Perotti, Qin Yi +1
This paper introduces a novel physical-layer method labelled as Multi-Modal Concurrent Transmission (MMCT) for efficient transmission of multiple data streams with different reliab…
Feedback is Good, Active Feedback is Better: Block Attention Active Feedback Codes
Emre Ozfatura, Yulin Shao, Amin Ghazanfari +3
Deep neural network (DNN)-assisted channel coding designs, such as low-complexity neural decoders for existing codes, or end-to-end neural-network-based auto-encoder designs are ga…
All you need is feedback: Communication with block attention feedback codes
Emre Ozfatura, Yulin Shao, Alberto Perotti +2
Deep learning based channel code designs have recently gained interest as an alternative to conventional coding algorithms, particularly for channels for which existing codes do no…
AttentionCode: Ultra-Reliable Feedback Codes for Short-Packet Communications
Yulin Shao, Emre Ozfatura, Alberto Perotti +2
Ultra-reliable short-packet communication is a major challenge in future wireless networks with critical applications. To achieve ultra-reliable communications beyond 99.999%, this…
DRF Codes: Deep SNR-Robust Feedback Codes
Mahdi Boloursaz Mashhadi, Deniz Gunduz, Alberto Perotti +1
We present a new deep-neural-network (DNN) based error correction code for fading channels with output feedback, called deep SNR-robust feedback (DRF) code. At the encoder, parity…
Spatial-Interference Aware Cooperative Resource Allocation for 5G NR Sidelink Communications
Silvia Mura, Francesco Linsalata, Marouan Mizmizi +5
Distributed resource allocation (RA) schemes have been introduced in cellular vehicle-to-everything (C-V2X) standard for vehicle-to-vehicle (V2V) sidelink (SL) communications to sh…
LoS-Map Construction for Proactive Relay of Opportunity Selection in 6G V2X Systems
Francesco Linsalata, Silvia Mura, Marouan Mizmizi +5
Recent advances in Vehicle-to-Everything (V2X) technology and the upcoming sixth-generation (6G) network will dawn a new era for vehicular services with enhanced communication capa…
Accumulative Iterative Codes Based on Feedback
Alberto G. Perotti, Branislav M. Popovic, Anahid R. Safavi
The Accumulative Iterative Code (AIC) proposed in this work is a new error correcting code for channels with feedback. AIC sends the information message to the receiver in a number…
Deep Extended Feedback Codes
Anahid Robert Safavi, Alberto G. Perotti, Branislav M. Popovic +2
A new deep-neural-network (DNN) based error correction encoder architecture for channels with feedback, called Deep Extended Feedback (DEF), is presented in this paper. The encoder…
Non-Orthogonal Multiple Access for Degraded Broadcast Channels: RA-CEMA
Alberto G. Perotti, Branislav M. Popovic
A new non-orthogonal multiple access scheme performing simultaneous transmission to multiple users characterized by different signal-to-noise ratios is proposed. Different users ar…
Enhanced Trellis Coded Multiple Access (ETCMA)
Alberto G. Perotti, Branislav M. Popovic
We propose an enhanced version of trellis coded multiple access (TCMA), an overloaded multiple access scheme that outperforms the original TCMA in terms of achieved spectral effici…
Capacity-achieving CPM schemes
Alberto Perotti, Alberto Tarable, Sergio Benedetto +1
The pragmatic approach to coded continuous-phase modulation (CPM) is proposed as a capacity-achieving low-complexity alternative to the serially-concatenated CPM (SC-CPM) coding sc…
