Digital Precoding Design for MIMO System with One-Bit ADC Receivers
2019When wireless communication transmits in the bandwidth of gigahertz, radio-frequency (RF) chains and high-resolution analog-to-digital converters (ADCs) increasingly bring burdens to energy consumption. To solve this problem, promising techniques are to use low-resolution ADCs and hybrid precoding architectures. In this work, we combine these solutions

Noise-Aided Demodulation with One-Bit ADC for Quadrature Amplitude Modulated Signals
2018 IEEE Global Communications Conference (GLOBECOM), 2018This paper proposes a new demodulation method using a one-bit analog-to-digital converter (ADC). With one bit resolution, a signal having a multilevel signal, such as a quadrature amplitude modulated (QAM) signal, is largely degraded by nonlinearity. To demodulate the signals, a high- resolution ADC is used to receive the signals with high linearity ...

Secrecy Capacity of a Gaussian Wiretap Channel with One-bit ADCs is Always Positive
2019 IEEE Information Theory Workshop (ITW), 2019We consider the Gaussian wiretap channel with one-bit analog-to-digital converters (ADCs) at both the legitimate receiver and the eavesdropper. In this channel, we show that a positive secrecy rate is always achievable whenever the noise power $n_{1}^{2}$ at the legitimate receiver is not the same as the noise power $n_{2}^{2}$ at the eavesdropper.

AoAs and AoDs estimation for sparse millimeter wave channels with one-bit ADCs
2016 8th International Conference on Wireless Communications & Signal Processing (WCSP), 2016Millimeter wave (mmWave) communication is favored for its abundant bandwidth. However, the sampling rate scales up with the large bandwidth, thus making it difficult to implement high-resolution analog-to-digital converters (ADCs). In addition, a large-scale array is employed to overcome the high path loss of the mmWave channels.

Rate Analysis of Cell-Free Massive MIMO with One-Bit ADCs and DACs
2019 IEEE 30th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2019We investigate the downlink rate performance of cell-free massive multiple-input multiple-output (mMIMO) network with conjugate beamforming precoder when the access points (APs) are equipped with one-bit analog-digital converters (ADCs) and digital-analog converters (DACs).

Soft-Output Detector for Uplink MU-MIMO Systems With One-Bit ADCs
IEEE Communications Letters, 2018We consider an uplink multiuser multiple-input multiple-output (MU-MIMO) system with one-bit analog-to-digital converters (ADCs). In this system, numerous symbol detectors, such as maximum-likelihood, zero-forcing, and supervised-learning-based detectors, have been proposed by using one-bit quantized channel outputs.

Uplink Performance Analysis of Oversampled Wideband Massive MIMO with One-Bit ADCs
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018Use of 1-bit analog-to-digital converters in massive multiple-input multiple-output (MIMO) systems has been investigated widely due to the very low power consumption and implementation complexity they have. In this study, we present the benefits of temporal oversampling at the receiver side in 1-bit quantized uplink wideband massive MIMO systems.
