Combination of SCMA and MIMO with antenna selection

Non–orthogonal multiple access is a key technology for implementation in next generation mobile communication standards. The implementation of NOMA technology requires coordination with already used and well-proven technologies, such as the technology of multi-antenna systems. The combination of MIMO and NOMA technologies provides to ensure efficient use of the radio frequency spec-trum through spatial signal processing and high network capacity due users’ signal processing in overload mode. There are several types of NOMA technology, each of them can be combined with MIMO technology, taking into account the special features of both technologies. Sparce code multiple access is one of the most prom-ising type of NOMA technology. The main goal of this article is to analyze the pos-sibility of combining SCMA technology with MIMO technology in the antenna se-lection mode to organize spatial orthogonal resources as one of the possible options for combination of these technologies for next-generation mobile communication systems. The results of computer modeling confirm the effectiveness of the joint use of SCMA and MIMO in antenna selection mode.
