Spectral Efficiency Maximization for STAR-RIS-Assisted mmWave-NOMA Downlink Communication Systems
Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) can reconstruct indirect links when the direct link is blocked for millimeter wave (mmWave) communications. Moreover, the spectral efficiency of non-orthogonal multiple access (NOMA) can benefit from the highly directional transmis...
