Channel Estimation via Gradient Pursuit for MmWave Massive MIMO Systems with One-Bit ADCs
In-soo Kim, Junil Choi
In millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, one-bit analog-to-digital converters (ADCs) are employed to reduce the impractically high power c…
Channel Estimation for Spatially/Temporally Correlated Massive MIMO Systems with One-Bit ADCs
Hwanjin Kim, Junil Choi
This paper considers the channel estimation problem for massive multiple-input multiple-output (MIMO) systems that use one-bit analog-to-digital converters (ADCs). Previous channel…
FCFGS-CV-Based Channel Estimation for Wideband MmWave Massive MIMO Systems with Low-Resolution ADCs
In-soo Kim, Junil Choi
In this paper, the fully corrective forward greedy selection-cross validation-based (FCFGS-CV-based) channel estimator is proposed for wideband millimeter wave (mmWave) massive mul…
Gradient Pursuit-Based Channel Estimation for MmWave Massive MIMO Systems with One-Bit ADCs
In-soo Kim, Junil Choi
In this paper, channel estimation for millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems with one-bit analog-to-digital converters (ADCs) is considered.…
Efficient Channel AoD/AoA Estimation Using Widebeams for Millimeter Wave MIMO Systems
Hyeongtaek Lee, Sucheol Kim, Junil Choi
Using millimeter-wave (mmWave) bands is expected to provide high data rates through large licensed and unlicensed spectrum. Due to large path loss and sparse scattering propagation…
