Three-Dimensional Spatial Correlation Modeling for Cylindrical mMIMO Arrays in HAPS
Shasha Liu, Abla Kammoun, Mohamed-Slim Alouini
High-altitude platform stations (HAPS) are envisioned as a key component of future wireless networks, enabling ultra-wide coverage and providing direct connectivity to users with cylindrical massive multiple-input multiple-output (mMIMO) systems. Exploiting the channel degrees of…
