BeamGuard: Risk-Aware Multimodal Beam Forecasting and Adaptive Virtual Beamwidth Control for 6G mmWave V2I Links
Abidemi Orimogunje, Dejan Vukobratovic, Sunwoo Kim +4
Reliable beam management is a central challenge for 6G millimeter-wave (mmWave) vehicle-to-infrastructure (V2I) links, where narrow beams provide high array gain but are vulnerable…
Multi-Chirp AFDM for Rydberg Atomic Quantum Receivers: Waveform and Algorithm Design
Hanvit Kim, Hyeon Seok Rou, Kihong Min +2
We propose a multi-chirp affine frequency division multiplexing (MC-AFDM) scheme for joint delay-Doppler estimation with Rydberg atomic quantum receivers (RAQRs). The work is motiv…
The Resurrection of Spectrum Spreading for 6G and Beyond: From Sinusoids to Chirps
Hyeon Seok Rou, Giuseppe Thadeu Freitas de Abreu, Emil Björnson +2
Orthogonal frequency-division multiplexing (OFDM) and its sinusoidal subcarriers have underpinned the 4G and 5G eras, delivering high spectral efficiency and resilience to multipat…
End-to-end Feature Alignment: A Simple CNN with Intrinsic Class Attribution
Parniyan Farvardin, David Chapman
We present Feature-Align CNN (FA-CNN), a prototype CNN architecture with intrinsic class attribution through end-to-end feature alignment. Our intuition is that the use of unordere…
System-Level Comparison of Multimodal and In-Band mmWave Sensing for Beam Prediction in 6G ISAC
Abidemi Orimogunje, Hyunwoo Park, Igbafe Orikumhi +2
Integrated sensing and communication (ISAC) can reduce beam-training overhead in mmWave vehicle-to-infrastructure (V2I) links by enabling in-band sensing-based beam prediction, whi…
