Query: Performance Analyses of TAS/Alamouti-MRC NOMA in Dual-Hop Full-Duplex AF
  Relaying Networks   In this paper, the performance of a power domain downlink multiple-input
multiple-output non-orthogonal multiple access system in dual-hop full-duplex
(FD) relaying networks is investigated over Nakagami-$m$ fading channels by
considering the channel estimation error and feedback delay. Particularly, in
the investigated system, the base station equipped with multiple antennas
transmits information to all mobile users by applying conventional transmit
antenna selection/Alamouti-space-time block coding scheme with the help of a
dedicated FD amplify-and-forward relay. The received signals at mobile users
are combined according to maximal-ratio combining technique to exploit benefits
of receive diversity. In order to demonstrate the superiority of the proposed
system, outage probability (OP) is investigated and tight lower bound
expressions are derived for the obtained OP. Moreover, asymptotic analyses are
also conducted for ideal and practical conditions to provide further insights
about the outage behavior in the high signal-to-noise ratio region. Finally,
theoretical analyses are validated via Monte Carlo simulations and software
defined radio based test-bed implementation.
