Multipair Massive MIMO Relaying Systems with One-Bit ADCs and DACs
IEEE Trans. Signal Process., 2017 This paper considers a multipair amplify-and-forward massive MIMO relaying system with one-bit ADCs and one-bit DACs at the relay. The channel state information is estimated via pilot training, and then utilized by the relay to perform simple maximum-ratio combining/maximum-ratio transmission processing.

One-bit ADCs in wideband massive MIMO systems with OFDM transmission
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016 We investigate the performance of wideband massive MIMO base stations that use one-bit ADCs for quantizing the uplink signal. Our main result is to show that the many taps of the frequency-selective channel make linear combiners asymptotically consistent and the quantization noise additive and Gaussian, which simplifies signal processing and enables ...

On Multiterminal Communication over MIMO Channels with One-bit ADCs at the Receivers [PDF]
2019 IEEE International Symposium on Information Theory (ISIT), 2019 The fundamental limits of communication over multiple-input multiple-output (MIMO) networks are considered when a limited number of one-bit analog to digital converters (ADC) are used at the receiver terminals. Prior works have mainly focused on point-to-point communications, where receiver architectures consisting of a concatenation of an analog ...

Amplitude Retrieval for Channel Estimation of MIMO Systems With One-Bit ADCs
IEEE Signal Processing Letters, 2019 This letter revisits the channel estimation problem for MIMO systems with one-bit analog-to-digital converters (ADCs) through a novel algorithm--Amplitude Retrieval (AR). Unlike the state-of-the-art methods such as those based on one-bit compressive sensing, AR takes a different approach.
