Robust Beamforming for Nonorthogonal Multiple-Access Systems in MISO Channels

Nonorthogonal multiple access (NOMA) is a promising technology in future mobile communication systems. In this paper, considering that the base station knows imperfect channel state information (CSI), we investigate the robust beamforming design problem for NOMA systems in multiple-input-single-outp...
