Recently, the symmetric superposition coding (SSC) [3] is proposed for a solution for the error propagation (EP)due to the non-perfect successive interference cancelation (SIC) in non-orthogonal multiple access (NOMA). Weanalyze the performance of NOMA with the SSC. It is shown that the performance of the SSC NOMA is the sameas that of NOMA with the normal superposition coding (NSC) for the power allocation factor less than 20%, theSSC NOMA performance is better than the NSC NOMA performance up to the power allocation factor 80%, and theSSC NOMA performs worse than the NSC NOMA for the power allocation factor greater than 80%. As a result, theSSC should be used with consideration of the power allocation.
