Multiuser MIMO-AFDM Beamforming for ISAC in Doubly Dispersive Channels
Rang Liu, Ming Li, A. Lee Swindlehurst, Norman Franchi, Robert Schober
Integrated sensing and communication (ISAC) in high-mobility channels requires waveform and beamforming designs that are robust to delay-Doppler dispersion. With this in mind, in this paper we study a monostatic multiuser multiple-input multiple-output (MIMO) affine frequency div…
