Joint source-channel coding with one-bit ADC front end [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper considers the zero-delay transmission of a Gaussian source over an additive white Gaussian noise (AWGN) channel with a one-bit analog-to-digital converter (ADC) front end. The optimization of the encoder and decoder is tackled under both the mean squared error (MSE) distortion and the outage distortion criteria with an average power ...

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.

One-Bit Sphere Decoding for Uplink Massive MIMO Systems With One-Bit ADCs
IEEE Transactions on Wireless Communications, 2018 This paper presents a low-complexity near-maximum-likelihood-detection (near-MLD) algorithm called one-bit-sphere-decoding for an uplink massive multiple-input multiple-output (MIMO) system with one-bit analog-to-digital converters (ADCs). The idea of the proposed algorithm is to estimate the transmitted symbol vector sent by uplink users (a codeword ...

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.

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 ...
