Short-Boundary Signaling for Asynchronous Grant-Free Control-to-Control Communications
Massimo Battaglioni, Dania De Crescenzo, Edoardo Carnevali +1
In asynchronous grant-free access, receivers must detect variable-length transmissions and identify their start and end. Existing decoder-aided receivers use start and tail sequenc…
A Deep Learning-based Receiver for Asynchronous Grant-Free Random Access in Control-to-Control Networks
Massimo Battaglioni, Edoardo Carnevali, Dania De Crescenzo +3
In this paper, we study grant-free, asynchronous control-to-control (C2C) communications in an indoor scenario with a shared wireless channel. Each communication node transmits com…
Complex Approximate Message Passing with Non-separable Denoising
Vishnu Teja Kunde, Alessandro Mirri, Jean-Francois Chamberland +1
Approximate Message Passing (AMP) is a general framework for iterative algorithms, originally developed for compressed sensing and later extended to a wide range of high-dimensiona…
Approximate Message Passing for Multi-Preamble Detection in OTFS Random Access
Alessandro Mirri, Vishnu Teja Kunde, Enrico Paolini +1
This article addresses the problem of multiple preamble detection in random access systems based on orthogonal time frequency space (OTFS) signaling. This challenge is formulated a…
