Abstract

Since a sufficient condition on the larger rate volume of 3-user correlated information sources (CIS)/non-successive interference cancellation (SIC) non-orthogonal multiple access (NOMA) over independent information sources (IIS)/SIC NOMA has not been investigated, this paper analyzes such a sufficient condition. First, we demonstrates that the rate volume of 3-user CIS/SIC NOMA is the same as a portion of the rate volume of 3-user IIS/SIC NOMA. Then, by identifying a dominant rate region, we calculate the sufficient condition on the larger rate volume of 3-user CIS/non-SIC NOMA over 3-user IIS/SIC NOMA. We also show that with such condition, the rate volume of 3-user CIS/non-SIC NOMA can be larger than that of 3-user IIS/SIC NOMA.

삼중 사용자 CIS/non-SIC 비직교 다중 접속의 IIS/SIC 비직교 다중 접속에 대한 확대된 전송률 용적의 충분조건에 대한 연구가 미비하여, 본 논문은 그러한 충분조건을 분석한다. 먼저, 삼중 상관 정보원/SIC 비직교 다중 접속의 전송률 용적이 삼중 독립 정보원/SIC 비직교 다중 접속의 전송률 용적의 일부와 일치하는 것을 입증한다. 다음, 우세 전송률 영역을 확인함으로써, 삼중 상관 정보원/non-SIC 비직교 다중 접속이 상중 독립 정보원/SIC 비직교 다중 접속에 대한 확대된 전송률 용적의 충분조건을 계산한다. 또한, 분석된 조건을 기반으로, 삼중 상관 정보원/non-SIC 비직교 다중 접속의 전송률 용적이 삼중 독립 정보원/SIC 비직교 다중 접속의 전송률 용적보다 확대될 수 있음을 보여준다.
