DOI: 10.1109/twc.2025.3611629
Abstract: Terahertz (THz) massive multiple-input multiple-output (mMIMO) systems offer ultra-high data rates but face significant challenges such as beam squint effects, high power consumption, severe path loss, and signal blockage. Incorporating reconfigurable intelligent surfaces (RIS) can… read more here.
