BER Performance Analysis of Asynchronous NOMA with Arbitrary Phase Offset
文献摘要：
An asynchronous transmission scenario for non-orthogonal multiple access(NOMA)user signals with arbitrary phase offset is investigated in this pa-per.To improve the system performance in the user power-balanced conditions,we adopt a synthetic de-tection method at the receiver,i.e.,the jointly optimal maximal likelihood detection aided triangular succes-sive interference cancellation(JO ML-TSIC)method.Analytical bit error rate(BER)solutions are obtained for a two-user case with the optimal,intentional one-half symbol period time delay implemented between the user signals.Furthermore,closed-form BER solu-tions for the case using the triangular successive inter-ference cancellation(TSIC)detection method are also derived for comparisons.Numerical results show that the JO ML-TSIC receiver for the asynchronous sys-tem outperforms the TSIC receiver as well as the syn-chronous successive interference cancellation(SIC)receiver in all the conditions concerned.The results also show that the superiority of the JO ML-TSIC re-ceiver is strengthened when the signals experience flat Rayleigh fading channels compared to the TSIC and the synchronous SIC receivers.
