Performance Analysis of the Reconfigurable Intelligent Surfaces Communication SystemsOA

Reconfigurable intelligent surfaces(RIS)play a vital role in meeting the growing demand for higher data rates and reliability in wireless systems.This study focuses on analyzing the performance of RIS systems to gain a deeper understanding of their potential.The paper presents a mathematical analysis of the RIS system,deriv-ing closed-form formulae that express its characteristics including signal-to-noise ratio(SNR)distribution,ergodic and effective capacity,outage,and error probability.The obtained formulae are newly derived and unconditionally valid solutions.Numerical results demonstrate a close agreement between the derived formulae and Monte-Carlo simulation outcomes.
