Abstract
In this paper, we analyze the system performance of a large intelligent surface (LIS) enabled wireless system over Nakagami-m channels. We derive closed-form expressions of the outage probability, ergodic capacity, and average bit error rate using different approximation methods, namely, central limit theorem (CLT), Gamma and generalized-K$(K_{\mathrm{G}})$. The effects of a number of passive LIS pixels$(N)$and fading parameters on the system performance are examined. Results show that the Gamma and$K_{\mathrm{G}}$approximations are precise given different values of$N$, while the CLT approximation's accuracy depends on the number of LIS elements implemented. Finally, analytical findings are validated by thorough Monte Carlo simulations.
