Abstract

In the fifth generation (5G) mobile networks, the mobile services require 100 times faster connections. One of the promising 5G technologies is non-orthogonal multiple access (NOMA). In NOMA, the users share the channel resources, so that the more users can be served simultaneously. There are several advantages offered by NOMA, such as higher spectrum efficiency and low transmission latency, compared to orthogonal multiple access (OMA), which is usually used in the fourth generation (4G) mobile networks, for example, long term evolution (LTE). In this paper, we compare the receivers for NOMA. The standard NOMA receiver, the non-SIC NOMA receiver, and the symmetric superposition coding (SC) NOMA receiver are compared. Specifically, it is shown that the performance of the standard receiver is the best, whereas the performances of the non-SIC receiver and symmetric SC receiver are dependent on the power allocation.

5G 이동 통신 시스템에서는, 통신 서비스가 100배 빠른 망 연결을 연구한다. 비직교 다중접속은 선도적인 5G 기술들 중 하나로 주목받고 있다. 비직교 다중접속에서는 사용자들이 채널 자원들을 공유하여, 더 많은 사용자들이 동시에 서비스를 받을 수가 있다. LTE와 같은 4G 이동 통신에서 사용되는 직교 다중접속과 비교하면, 비직교 다중접속은 높은 주파수 효율과 초저 지연과 같은 장점을 가진다. 본 논문에서는 비직교 다중접속의 수신기들을 비교한다. 표준 수신기, SIC를 수행하지 않는 수신기, 그리고 대칭 중첩 코딩 수신기가 비교된다. 구체적으로, 표준 수신기의 성능이 가장 우수하며, SIC를 수행하지 않는 수신기, 그리고 대칭 중첩 코딩 수신기의 성능은 전력 할당에 따라 달라지는 성능 분석을 본 논문에서 고찰한다.
