摘要: Cooperative non-orthogonal multiple access (NOMA) systems inherit advantages of the NOMA protocol and cooperative relay. In this paper, we propose in multiple-input-multiple-output channels. The whole transmission is divided into two phases. first phase, base station broadcasts signals using to a central user cell-edge user. second helps cooperatively relay intended for Our objective maximize achievable rate from under transmit power constraints constraint difficulty problem joint beamforming phase. We constrained convex-concave procedure (CCCP)-based algorithm. To reduce computational complexity, also closed-form search-based suboptimal Simulation results demonstrate that our proposed system with CCCP-based algorithm outperforms conventional scheme. When low,
