主　　题：NOMA bit error rate relay decoding error imperfect SIC 

摘      要：In contrast with orthogonal multiple access(OMA)technologies,non-orthogonal multiple access(NOMA)technology can achieve higher spectral effi-ciency and support more users *** relays can be deployed in NOMA networks,in order to combat fading and thus increase the transmission *** the existing works on cooperative NOMA networks with multiple relays,the decoding error at the relays and the imperfect successive interference cancellation(SIC)are not taken into account *** this work,we consider the bit error rate(BER)analysis of relay-aided NOMA networks,where max-min relay selection is ***,closed-form BER expressions are derived for NOMA networks with Rayleigh fading,in the existence of the relay decoding error and imperfect *** asymptotic BER performance is then obtained to provide some useful insights into the system design such as the diversity ***,simulation results illustrate the correctness of the derived *** presented results reveal the effects of imperfect SIC and relay decoding error on the performance of cooperative NOMA networks.
