Технологія NOMA та переваги неортогонального розділення абонентів

Abstract

This work is devoted the Non-Orthogonal Multiple Access (NOMA) technology is aimed at increasing the spectral efficiency of wireless communication systems and enabling the operation of a large number of subscriber devices, as well as flexible resource utilization. For decades, radio communication systems with orthogonal signal separation have been used, where each subscriber is allocated their own resource in the frequency or time domain. However, orthogonal multiple access does not meet the requirements of future wireless networks (be yond 5G), especially for the mMTC scenario, where mass device connectivity with high connection density per square kilometer needs to be ensured.
