Learning to Reflect and to Beamform for Intelligent Reflecting Surface with Implicit Channel Estimation
Tao Jiang, Hei Victor Cheng, Wei Yu
Intelligent reflecting surface (IRS), which consists of a large number of tunable reflective elements, is capable of enhancing the wireless propagation environment in a cellular ne…
Channel Estimation for Reconfigurable Intelligent Surface Aided Multi-User mmWave MIMO Systems
Jie Chen, Ying-Chang Liang, Hei Victor Cheng +1
Channel acquisition is one of the main challenges for the deployment of reconfigurable intelligent surface (RIS) aided communication systems. This is because an RIS has a large num…
Optimal Hybrid Beamforming for Multiuser Massive MIMO Systems With Individual SINR Constraints
Guangda Zang, Ying Cui, Hei Victor Cheng +3
In this letter, we consider optimal hybrid beamforming design to minimize the transmission power under individual signal-to-interference-plus-noise ratio (SINR) constraints in a mu…
