Efficient transmission in the millimeter waves 28 GHz Outdoor Channel Using Spatial Multiple Access (SMA) NonOrthogonal Multiple Access (NOMA) is considered as one of the key technologies for the fifth generation (5G) of the cellular networks. However, due to the complexity of the Successive Interference, spatial multiple access (SMA) technique xe2x80x93 based on using spatial modulation for multiple antenna systems xe2x80x93 was proposed to avoid the use of successive interference cancellation. On the other hand, millimeter waves band is a promising band for 5G. this is mainly because the traditional microwave band is currently fully crowded. In this paper we investigate efficient transmission in the millimeter waves 28 GHz Outdoor Channel Using Spatial Multiple Access (SMA). Two ray fluctuating model (TRF) is used in the performance analysis for millimeter waves, as well as the limiting case of the Rayleigh channel. Analytical and simulation results show the performance of SMA over millimeter waves. Finally; the performance is shown to be improved over the more complicated NOMA with SIC

Performance Evaluation of MIMONOMA 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 largevolume content services can be improved. This paper proposes to exploit the joint benefits of mmWave and codedomain 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.
