Abstract: Affine Frequency Division Multiplexing (AFDM), a new chirp-based multicarrier waveform for high mobility communications, is introduced here. AFDM is based on discrete affine Fourier ...
Abstract: This work proposes an area-efficient 28-GHz time-division MIMO beamformer without additional hardware cost. RF signal paths can be reused for different MIMO streams by a time-division ...
