  In this paper we investigate the achievable rate of LOS MIMO systems that use
1-bit quantization and spatial oversampling at the receiver. We propose that by
using additional antennas at the receiver, the loss incurred due to the strong
limitation of the quantization can be decreased. Mutual information results
show that considerable rate gains can be achieved depending on the number and
arrangement of the antennas. In some of the cases, even the full available rate
from the transmitter can be attained. Furthermore, the results also reveal that
two-dimensional antenna arrays can benefit more from spatial oversampling than
one-dimensional arrays, when using 1-bit quantization in the LOS MIMO scenario.
