Uplink Performance of RIS-aided Cell-Free Massive MIMO System Over Spatially Correlated Channels
Enyu Shi, Jiayi Zhang, Zhe Wang +2
We consider a practical spatially correlated reconfigurable intelligent surface (RIS)-aided cell-free (CF) massive multiple-input-multiple-output (mMIMO) system with multi-antenna…
Extremely Large-Scale MIMO: Fundamentals, Challenges, Solutions, and Future Directions
Zhe Wang, Jiayi Zhang, Hongyang Du +4
Extremely large-scale multiple-input-multiple-output (XL-MIMO) is a promising technology to empower the next-generation communications. However, XL-MIMO, which is still in its earl…
Cell-Free Massive MIMO with Multi-Antenna Users over Weichselberger Rician Channels
