ESTRADA BRITO, Néstor  and  MORALES ALARCON, Cristian. Non-orthogonal multiple access technique performance in a Long-Term Evolution mobile communication system. Novasinergia [online]. 2020, vol.3, n.1, pp.62-76. ISSN 2631-2654.

The growing demand for data through mobile networks and the search for more efficient services by users have led to new techniques that increase spectral efficiency. Non-orthogonal multiple access (NOMA) is one of the techniques being evaluated within the 3GPP (Third Generation Partnership Project). It provides services to multiple users through potential multiplexing. This research evaluates the performance of NOMA in LTE (Long Term Evolution) systems through physical layer simulations in relation to conventional orthogonal multiple access technologies TDM (Time Division Multiplexing) and FDM (Frequency Division Multiplexing). The profits obtained will be compared with those published in the Advanced Television Systems Committee (ATSC) 3.0 bibliography. The results show that NOMA is better than TDM when a low rate is used in the mobile receiver. An average rate in the fixed receiver showed gains of 3.35dB and 0.25dB, respectively.

Keywords : ATSC 3.0; LDM; LTE; NOMA; spectral efficiency.
