Uplink Performance of Wideband Massive MIMO With One-Bit ADCs
IEEE Transactions on Wireless Communications, 2017 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.

Channel Estimation in MIMO Systems With One-Bit Spatial Sigma-Delta ADCs
IEEE Transactions on Signal Processing, 2022 This paper focuses on channel estimation in single-user and multi-user MIMO systems with multi-antenna base stations equipped with 1-bit spatial sigma-delta analog-to-digital converters (ADCs). A careful selection of the quantization voltage level and phase shift used in the feedback loop of 1-bit sigma-delta ADCs is critical to improve its effective ...

Target Detection Performance of Collocated MIMO Radar With One-Bit ADCs
IEEE Signal Processing Letters, 2019It is known that deploying low-resolution (e.g., one-bit) analog-to-digital converters (ADCs) at the receive antennas can reduce the hardware cost and circuit power consumption, especially for large-scale systems. In this context, we investigate the performance of target detection for collocated multiple-input multiple-output (MIMO) radar with one-bit ...

One-Bit ΣΔ-Encoded Stimulus Generation for On-Chip ADC Test
Journal of Circuits, Systems and Computers, 2020This paper presents an application of the [Formula: see text] modulation technique to the on-chip dynamic test for analog-to-digital converters (ADCs). The required stimulus such as a single- or two-tone signal is encoded into one-bit [Formula: see text] sequence, which is applied to an ADC under test through a driving buffer and a simple low-pass ...

Learning From Noisy Labels for MIMO Detection With One-Bit ADCs
IEEE Wireless Communications Letters, 2023This paper presents a data detection method for multiple-input multiple-output systems with one-bit analog-to-digital converters. The basic idea is to learn the likelihood function of the system from training samples. To this end, a training data generation strategy is first proposed, which labels a one-bit received signal with a symbol index ...

On the Performance of Cell -Free Massive MIMO with One-Bit ADCs and DACs
2019 IEEE/CIC International Conference on Communications in China (ICCC), 2019In this paper, we consider a downlink cell-free massive multiple-input multiple-output (mMIMO) system with conjugate beamforming precoder, where each access point (AP) is equipped with one-bit analog-digital converters (ADCs) and digital-analog converters (DACs) and each user is equipped with one-bit ADCs. Based on the Bussgang decomposition theory, we
