MA-Aided Hierarchical Hybrid Beamforming for Multi-User Wideband Beam Squint Mitigation
Cixiao Zhang, Yin Xu, Xinghao Guo +3
In wideband near-field arrays, frequency-dependent array responses cause wavefronts at different frequencies to deviate from that at the center frequency, producing beam squint and…
Preconditioned Conjugate Gradient for MIMO-AFDM System
Jun Zhu, Yin Xu, Dazhi He +3
Affine frequency division multiplexing (AFDM) is a promising chirp-assisted multicarrier waveform for future high mobility communications. A significant challenge in MIMO-AFDM syst…
