Abstract

In this paper, we study the joint impact of nodes' mobility and channel estimation error (CEE) on the performance of non-orthogonal multiple access aided vehicular communication system. Specifically, we derive exact outage probability expressions for both near user and far user vehicles over Nakagami-m fading channels. We then analyze the asymptotic outage behavior in the high signal-to-noise ratio regime, from which valuable insights related to system's diversity order are quantified. Furthermore, some special cases of interest are also formulated to quantify the impact of nodes's mobility and/or CEE on the system's outage performance. Analytical expressions of the average bit error rate and ergodic capacity for both near and far user vehicles are further derived under Nakagami-m fading channels. Finally, we corroborate our analytical findings with the numerical and simulation studies, and demonstrate the effects of transmit power, fading severity parameters, nodes' mobility parameters, and CEE parameters on the system's performance.
