Study on transmission over Nakagami-m fading channel for multiple access scheme without orthogonal signal
In this paper, a downlink performance in non-orthogonal multiple access
(NOMA) system is considered. With regard to different priority for two
NOMA users, we exploit the closed-form expressions of outage probability over wireless fading channel…
