Holographic Beamforming for Range-Doppler Sidelobe Suppression in OFDM-ISAC
Amirhossein Azarbahram, Onel L. A. López
This paper investigates range--Doppler (RD) sidelobe suppression in an integrated sensing and communications system with a reconfigurable holographic surface (RHS). We jointly desi…
Beam Selection for Delay-Doppler Visibility in Multi-Target MIMO-OFDM Sensing
Amirhossein Azarbahram, Onel L. A. López
This paper studies leakage-aware beam selection for multi-target multiple-input multiple-output (MIMO)-orthogonal frequency-division multiplexing (OFDM) sensing. We focus on ensuri…
Sequential Monte Carlo for Resilient Networks: Assessment, Mitigation, and Generative Modeling
Onel L. A. López, Amirhossein Azarbahram
Resilience is becoming crucial for future wireless networks, which must withstand, adapt to, and recover from rare but potentially cascading disruptions. This paper develops a sequ…
Radio Stripe-Based Distributed ISAC System with Dynamic Sensing-Communication Reconfiguration
Osmel MartÃnez Rosabal, Onel L. Alcaraz López
Integrated sensing and communications (ISAC) has emerged as an intrinsic service of upcoming 6G wireless systems, enabling the reuse of communication signals for environmental sens…
Discrete Diffusion for Codebook-Based Beam Candidate Generation
Amirhossein Azarbahram, Onel L. A. López
Millimeter-wave (mmWave) communication enables high data rates through large bandwidths and highly directional beamforming, but its sensitivity to blockage and mobility makes relia…
Sequential Monte Carlo for Network Resilience Assessment and Control
Onel Luis Alcaraz López
Resilience is emerging as a key requirement for next-generation wireless communication systems, requiring the ability to assess and control rare, path-dependent failure events aris…
