Query: Uplink Performance of Wideband Massive MIMO with One-Bit ADCs   Analog-to-digital converters (ADCs) stand for a significant part of the total
power consumption in a massive MIMO base station. One-bit ADCs are one way to
reduce power consumption. This paper presents an analysis of the spectral
efficiency of single-carrier and OFDM transmission in massive MIMO systems that
use one-bit ADCs. A closed-form achievable rate, i.e., a lower bound on
capacity, is derived for a wideband system with a large number of channel taps
that employs low-complexity linear channel estimation and symbol detection.
Quantization results in two types of error in the symbol detection. The
circularly symmetric error becomes Gaussian in massive MIMO and vanishes as the
number of antennas grows. The amplitude distortion, which severely degrades the
performance of OFDM, is caused by variations between symbol durations in
received interference energy. As the number of channel taps grows, the
amplitude distortion vanishes and OFDM has the same performance as
single-carrier transmission. A main conclusion of this paper is that wideband
massive MIMO systems work well with one-bit ADCs.
