A Framework for Multi-Functional Optimization in RIS-Aided Hybrid Analog-Digital MIMO Systems

Both the reconfigurable intelligent surface (RIS) and the hybrid analog-digital antenna array have been envisioned as two cost-effective and promising technologies for achieving various types of functionality enhancement of future wireless systems. In this paper, we develop a framework for the multi...
