Millimeter wave (mmWave) is a viable technology
for future cellular systems. With bandwidths on the order of
a gigahertz, high-resolution analog-to-digital converters (ADCs)
become a power consumption bottleneck. One solution is to
employ very low resolution one-bit ADCs. This paper analyzes
the flat fading multiple-input multiple-output (MIMO) channel
with one-bit ADC. Bounds on the high signal-to-noise ratio (SNR)
capacity are derived for the single-input multiple-output (SIMO)
channel and the general MIMO channel. The results show how
the number of paths, number of transmit antennas, and number
of receive antennas impact the capacity at high SNR.
