Task-Based Quantization for Channel Estimation in RIS Empowered MmWave Systems
Gyoseung Lee, In-soo Kim, Yonina C. Eldar +4
In this paper, we investigate channel estimation for reconfigurable intelligent surface (RIS) empowered millimeter-wave (mmWave) multi-user single-input multiple-output communicati…
Gridless Channel Estimation for MmWave Hybrid Massive MIMO Systems with Low-Resolution ADCs
In-soo Kim, Junil Choi
This paper proposes the Newtonized fully corrective forward greedy selection-cross validation-based (NFCFGS-CV-based) channel estimator for millimeter (mmWave) hybrid massive multi…
Cell-Free MmWave Massive MIMO Systems with Low-Capacity Fronthaul Links and Low-Resolution ADC/DACs
In-soo Kim, Mehdi Bennis, Junil Choi
In this paper, we consider the uplink channel estimation phase and downlink data transmission phase of cell-free millimeter wave (mmWave) massive multiple-input multiple-output (MI…
Bayesian Channel Estimation for Intelligent Reflecting Surface-Aided mmWave Massive MIMO Systems With Semi-Passive Elements
In-soo Kim, Mehdi Bennis, Jaeky Oh +2
In this paper, we propose a Bayesian channel estimator for intelligent reflecting surface-aided (IRS-aided) millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) s…
Dominant Channel Estimation via MIPS for Large-Scale Antenna Systems with One-Bit ADCs
In-soo Kim, Namyoon Lee, Junil Choi
In large-scale antenna systems, using one-bit analog-to-digital converters (ADCs) has recently become important since they offer significant reductions in both power and cost. Howe…
