Abstract
This work proposes a wideband 26–33 GHz
multiple-input- multiple-output (MIMO) receiver (RX) array
that leverages time-modulation operation to achieve concurrent
steerable multibeam MIMOs (MB-MIMOs) using only one single
array beamformer. Time-modulated arrays (TMAs) introduce
time as an additional degree of freedom to concurrently sample
and multiplex multiple received signals in various incident angles.
In other words, time modulation on the RX array enables
spatial-spectral mapping that maps
