Özet
In this letter, outage probability (OP) of maximum-ratio transmission/receive antenna selection structure is analyzed in a single hop downlink multi-user multiple-input multiple-output non-orthogonal multiple access system. Theoretical analysis is conducted for Nakagami-m fading channels by considering residual hardware impairments (RHIs), channel estimation errors (CEEs) and imperfect successive interference cancellation (ipSIC) effects. Also, asymptotic OP expression is obtained to demonstrate the impact of practical impairments. According to theoretical results verified by Monte Carlo simulations, RHIs and ipSIC have only impact on array gain while CEEs cause zero diversity on the system performance.
