Performance Analysis of Holographic Surface Assisted Downlink NOMA with User Mobility

This work investigates the performance of a holo-graphic surface-aided downlink non-orthogonal multiple access (NOMA). We derive the analytical expression of outage probability considering mobility at both users. To account for user mobility, the sensing channels are modelled as time-selective with fading characteristics following a Nakagami-m distribution. The accuracy of derived expressions is validated using Monte Carlo (MC) simulations. Using the derived expressions, the impact of users mobility is demonstrated on the performance of the considered system model.
