  In this paper, we investigate a multi-cell millimeter wave (mmWave) massive
multiple-input multiple-output (MIMO) network with low-precision
analog-to-digital converters (ADCs) at the base station (BS). Each cell serves
multiple users and each user is equipped with multiple antennas but driven by a
single RF chain. We first introduce a channel estimation strategy for the
mmWave massive MIMO network and analyze the achievable rate with imperfect
channel state information. Then, we derive an insightful lower bound for the
achievable rate, which becomes tight with a growing number of users. The bound
clearly demonstrates the impacts of the number of antennas and the ADC
precision, especially for a single-cell mmWave network at low signal-to-noise
ratio (SNR). It characterizes the tradeoff among various system parameters. Our
analytical results are finally confirmed by extensive computer simulations.
