Abstract

Recently it has been proposed that lossless 2-user non-orthogonal multiple access (NOMA) can be implemented without successive interference cancellation (SIC) via correlated superposition coding (CSC). However only the 2-user case was considered. Thus this paper proposes a lossless 3-user non-SIC NOMA scheme. This can be achieved via the 3-user CSC scheme. Simulations show that the lossless 3-user non-SIC NOMA scheme can be implemented over power allocation ranges of user-fairness.

최근 상관 중첩 코딩으로 SIC를 사용하지 않고 무손실 이중 사용자 비직교 다중 접속이 구현될 수 있다고 보고된 바 있다. 그러나 단지 이중 사용자 사례만 고려되었다. 따라서 본 논문은 삼중 사용자 무손실 non-SIC 비직교 다중 접속 기법을 제안한다. 이러한 제안은 삼중 사용자 상관 중첩 코딩을 통하여 달성된다. 모의실험을 통해 삼중 사용자 무손실 non-SIC 비직교 다중 접속 기법이 사용자-공평성에 해당하는 전력 할당 영역에서 구현될 수 있음을 입증한다.
