Data-Aided Regularization of Direct-Estimate Combiner in Distributed MIMO Systems
To address this, we apply a regularization to the sample covariance matrix using a shrinkage coefficient based on the received data signal.
Uplink Transmit Power Optimization for Distributed Massive MIMO Systems with 1-Bit ADCs
First, in a scenario where a single RRH serves a single user equipment (UE), the signal-to-noise-and-distortion ratio (SNDR) is shown to be a non-monotonic and unimodal function of the UE transmit power due to the quantization distortion (QD).
Optimality of the Bussgang Linear MMSE Channel Estimator for MIMO Systems with 1-Bit ADCs
We compare the BLMMSE with the optimal minimum mean squared error (MMSE) channel estimator, which is generally non-linear, and we develop a novel framework based on the orthant probability of a multivariate normal distribution to compute the MMSE channel estimate.
Doubly 1-Bit Quantized Massive MIMO
Enabling communications in the (sub-)THz band will call for massive multiple-input multiple-output (MIMO) arrays at either the transmit- or receive-side, or at both.
Pilot-Based Uplink Power Control in Single-UE Massive MIMO Systems With 1-Bit ADCs
We propose uplink power control (PC) methods for massive multiple-input multiple-output systems with 1-bit analog-to-digital converters, which are specifically tailored to address the non-monotonic data detection performance with respect to the transmit power of the user equipment (UE).
Multi-User Data Detection in Massive MIMO with 1-Bit ADCs
We provide new analytical results on the uplink data detection in massive multiple-input multiple-output systems with 1-bit analog-to-digital converters.
A Variational Bayesian Perspective on Massive MIMO Detection
In this paper, we build upon variational Bayes (VB) inference to design low-complexity multiuser detection algorithms for massive MIMO systems.
Latency-Aware Multi-antenna SWIPT System with Battery-Constrained Receivers
Power splitting (PS) based simultaneous wireless information and power transfer (SWIPT) is considered in a multi-user multiple-input-single-output broadcast scenario.
Joint Minimum DL-UL Rate Maximization for Cell-Free Massive MIMO
Numerical results show that, in scenarios with short scheduling blocks, the proposed framework outperforms the case where the DL and UL beamforming strategies are computed individually via two separate bi-directional training phases thanks to the reduced training overhead.
Latency-Constrained Highly-Reliable mmWave Communication via Multi-point Connectivity
The sensitivity of millimeter-wave (mmWave) radio channel to blockage is a fundamental challenge in achieving low-latency and ultra-reliable connectivity.
Non-Symmetric Coded Caching for Location-Dependent Content Delivery
Immersive viewing is emerging as the next interface evolution for human-computer interaction.

Capacity Approaching Low Density Spreading in Uplink NOMA via Asymptotic Analysis
Conducting analysis in the regime where $F$, $K$, and ${d_k,\forall k}$ converge to $+\infty$ at the same rate, we present EMI as a deterministic equivalent plus a residual term.
Blockage-aware Reliable mmWave Access via Coordinated Multi-point Connectivity
The fundamental challenge of the millimeter-wave (mmWave) frequency band is the sensitivity of the radio channel to blockages, which gives rise to unstable connectivity and impacts the reliability of a system.
