摘要

In this paper, we investigate mmWave large-scale (LS) multiple-input multiple-output (MIMO) non-orthogonal multiple access (NOMA) systems with a sparse transmission scheme. For this system, we consider a NOMA technique with a user pairing scheme and a random beamforming technique to reduce the system overhead and achieve the desired communication link reliability. We formulate an optimization prob...
