A Comparison Between Co-Located and Distributed MIMO Deployments in OFDM-ISAC Networks
Maryam Darabi, Sergi Liesegang, Emanuele Grossi +1
This paper investigates network-level integrated sensing and communication (ISAC) under two fundamentally different topology configurations: cell-free massive MIMO (CF-mMIMO) and m…
Waveform Index Modulation for Backscatter Communications in RIS-Based MIMO Radars
Mehri Nikzad, Luca Venturino, Emanuele Grossi +1
This paper studies a symbiotic system in which a reconfigurable intelligent surface (RIS) assists a radar transmitter while conveying information to a reader via backscattering. Th…
Joint Detection and Velocity Estimation in OFDM-ISAC Cell-Free Massive MIMO Networks
Maryam Darabi, Sergi Liesegang, Emanuele Grossi +1
This paper develops a Doppler-aware sensing framework for cell-free massive MIMO (CF-mMIMO) networks operating under OFDM-based integrated sensing and communication (ISAC). The fra…
Integrated Communication and RIS-aided Track-Before-Detect Radar Sensing
Georgios Mylonopoulos, Luca Venturino, Emanuele Grossi +2
This paper investigates an integrated sensing and communication system where the base station serves multiple downlink users, while employing a passive reconfigurable intelligent s…
