Modular CSI Quantization for FDD Massive MIMO Communication
Jialing Liao, Roope Vehkalahti, Tefjol Pllaha +2
We consider high-dimensional MIMO transmissions in frequency division duplexing (FDD) systems. For precoding, the frequency selective channel has to be measured, quantized and fed…

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…
