Electromagnetic-Compliant Channel Modeling and Performance Evaluation for Holographic MIMO
Tengjiao Wang, Wei Han, Zhimeng Zhong +4
Recently, the concept of holographic multiple-input multiple-output (MIMO) is emerging as one of the promising technologies beyond massive MIMO. Many challenges need to be addresse…
Reconfigurable intelligent surfaces: Channel characterization and modeling
Jie Huang, Cheng-Xiang Wang, Yingzhuo Sun +5
Reconfigurable intelligent surfaces (RISs) are two dimensional (2D) metasurfaces which can intelligently manipulate electromagnetic waves by low-cost near passive reflecting elemen…
FDD Massive MIMO Uplink and Downlink Channel Reciprocity Properties: Full or Partial Reciprocity?
Zhimeng Zhong, Li Fan, Shibin Ge
One challenge for FDD massive MIMO communication system is how to obtain the downlink channel state information (CSI) at the base station. Except for traditional codebook feedback…
Deep Transfer Learning Based Downlink Channel Prediction for FDD Massive MIMO Systems
Yuwen Yang, Feifei Gao, Zhimeng Zhong +2
Artificial intelligence (AI) based downlink channel state information (CSI) prediction for frequency division duplexing (FDD) massive multiple-input multiple-output (MIMO) systems…
Extension of ITU IMT-A Channel Models for Elevation Domains and Line-of-Sight Scenarios
Zhimeng Zhong, Xuefeng Yin, Xin Li +1
In this contribution, the 3-dimensional (3D) channel characteristics, particularly in the elevation domains, are extracted through measurements in typical urban macro and micro env…
