By defining fundamental analytical equations, the outage probability of both mobile users is investigated via Monte Carlo simulations. Simulation results demonstrate that outage probability performance of the user with lower power allocation can be improved by the proposed technique, but it does not change for the other user.trinfo:eu-repo/semantics/closedAccessNon-orthogonal multiple accessAlamouti space-time block codingdual-hop systemtransmit antenna selectionConference Object2-s2.0-85100292883N/AWOS:000653136100127N/A
