Stacked Intelligent Metasurfaces for Holographic MIMO Aided Cell-Free Networks
Qingchao Li, Mohammed El-Hajjar, Chao Xu +3
Large-scale multiple-input and multiple-output (MIMO) systems are capable of achieving high date rate. However, given the high hardware cost and excessive power consumption of mass…
Stacked Intelligent Metasurface-Aided MIMO Transceiver Design
Jiancheng An, Chau Yuen, Chao Xu +5
Next-generation wireless networks are expected to utilize the limited radio frequency (RF) resources more efficiently with the aid of intelligent transceivers. To this end, we prop…
