Channel Estimation for RIS-Aided mmWave MIMO Systems
A reconfigurable intelligent surface (RIS) can shape the radio propagation by passively changing the directions of impinging electromagnetic waves. The optimal control […]
Short Range 3D MIMO mmWave Channel Reconstruction via Geometry-aided AoA Estimation
In some millimeter wave (mmWave) applications, such as wearables, the distance between the transceivers is relatively short. Further, the channel has significant […]
Low Complexity Sparse Channel Estimation for Wideband mmWave Systems
We consider the problem of channel estimation in hybrid transceiver architectures operating in millimeter wave (mmWave) band. Due to the dynamic features […]
