Query: Outage Behaviors of NOMA-based Satellite Network over Shadowed-Rician
  Fading Channels   This paper investigates the application of non-orthogonal multiple access
(NOMA) to satellite communication network over Shadowed-Rician fading channels.
The impact of imperfect successive interference cancellation (ipSIC) on
NOMA-based satellite network is taken into consideration from the perspective
of practical scenarios. We first derive new exact expressions of outage
probability for the p-th terrestrial user and provide the corresponding
asymptotic analysis results. The diversity order of zero and p are achieved by
the p-th terrestrial user with ipSIC and perfect successive interference
cancellation (pSIC), respectively. Finally, the presented simulation results
show that: 1) On the condition of pSIC, the outage behaviors of NOMA-based
satellite network are superior to that of orthogonal multiple access; 2) With
the value of residual interference increasing, the outage performance of
terrestrial users with ipSIC is becoming worse seriously; and 3) Infrequent
light shadowing of Shadowed-Rician fading brings the better outage probability
compared to frequent heavy and average shadowing.
