DOI: 10.1109/tccn.2022.3216406
Abstract: Reconfigurable intelligent surface (RIS) offers a potential performance boost for next-generation wireless networks, with significant improvements in spectral and energy efficiencies. In this paper, considering a two-user multiple-input single-output non-orthogonal multiple access (MISO-NOMA) downlink, we… read more here.

DOI: 10.23919/jcc.2020.06.007
Abstract: In this paper, we investigate the performance of commensal ambient back-scatter communications (AmBC) that ride on a non-orthogonal multiple access (NOMA) downlink transmission, in which a backscatter device (BD) splits part of its received signals… read more here.
