Abstract: 
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.
