Kurzfassung englisch:
Due to the small wavelengths at millimetre wave frequencies,
antenna arrays with dozens of elements fit easily even in hand-held
devices. As RF chains are power hungry and costly, all-digital ap-
proaches are impractical and analogue-digital co-designs are likely
to come. Common for all approaches is a dimensional reduction of
the large MIMO channel. This study compares Antenna Selection
(AS) and Hybrid Precoding (HP). In HP systems, channels are esti-
mated employing a set of hybrid codebooks exploiting all antennas.
For AS we propose a bistatic MIMO radar method to estimate the
channel even with a reduced number of antennas, identical to the
number of RF chains.
