  This work studies a multi-cell one-bit massive multiple-input multiple-output
(MIMO) system that employs one-bit analog-to-digital converters (ADCs) and
digital-to-analog converters (DACs) at each base station (BS). We utilize
Bussgang decomposition to derive downlink
signal-to-quantization-plus-interference-plus-noise ratio (SQINR) and ergodic
achievable rate expressions under one-bit quantized maximum ratio transmission
(MRT) and zero-forcing (ZF) precoding schemes considering scenarios with and
without pilot contamination (PC) in the derived channel estimates. The results
are also simplified for the mixed architecture that employs full resolution
(FR) ADCs and one-bit DACs, and the conventional architecture that employs FR
ADCs and DACs. The SQINR is shown to decrease by a factor of $2/\pi$ and
$4/\pi^2$ in the one-bit setting compared to that achieved in the mixed setting
and conventional setting respectively under MRT precoding without PC.
Interestingly, the decrease in SQINR is less when we consider PC, which is
shown to adversely impact the conventional system more than the one-bit system.
Similar insights are obtained under ZF precoding with the decrease in the SQINR
with the use of one-bit ADCs and DACs being more pronounced. We utilize the
derived expressions to yield performance insights related to power efficiency,
the numbers of antennas needed by the three architectures to achieve the same
sum-rate, and energy efficiency.
