Abstract
At present, the research about beamspace MIMO-NOMA system focus more on mathematical model. It is difficult to utilize this model in practice. To solve this problem, we decompose this system into four parts, that is beam selection, clustering, power allocation and precoding. Next we discuss the impact of beam selection and clustering on spectral efficiency (SE) and energy efficiency (EE) with a specified power allocation and precoding algorithm. The simulation result show that no scheme of system can outperform others in SE and EE in any environment.
