Performance Evaluation of MIMO-NOMA in Millimeter Wave Communication for Broadcast Services

With the development of broadcast video applications, the demand for broadcast video is increasing, which poses great challenges to the existing broadcast systems. The mmWave is capable of supporting large bandwidth. In addition, code domain NOMA is able to enhance the spectral efficiency. Therefore, combining the advantages of these two methods, the large-volume content services can be improved. This paper proposes to exploit the joint benefits of mmWave and code-domain NOMA to achieve further capacity gains in broadcast services. Theoretically analysis and numerical results validate the performance gain of the proposed scheme over conventional scheme with respect to spectral efficiency.
