This paper investigates the non-orthogonal multiple access (NOMA) scheme for correlated information sources (CIS), proposing a non-SIC NOMA scheme that allows all users to receive the common information. The data rate achieved by this non-SIC NOMA scheme is derived and the achievable rate region is analyzed. Numerical results confirm the effectiveness of the proposed non-SIC NOMA scheme compared to the conventional SIC NOMA scheme.
In this letter, the authors consider the non-orthogonal multiple access (NOMA) scheme for correlated information sources (CIS). We show that in the conventional NOMA scheme, the correlated information is not received by all the users, due to successive interference cancellation (SIC). Then the non-SIC NOMA scheme is proposed for all the users to receive the common information. The data rate achieved by this non-SIC NOMA scheme is derived. The achievable rate region is also analyzed. Numerical results validate the effectiveness of the proposed non-SIC NOMA scheme, compared to the conventional SIC NOMA scheme.
