Perfomance analysis of Intelligent Reflecting Surface-assisted Wireless Communications Under Various Application Scenarios

The Intelligent Reflecting Surface (1RS) or Reconflgurable Intelligent Surfaces (RIS) is one of the prospective technologies that might contribute to the next generation smart radio environment 1RS has the ability to dynamically alter wireless channels in order to optimise communication performance. Surfaces in a smart radio environment can actively influence channel realisation by controlling the propagation of incident electromagnetic waves in a programmable way, transforming the wireless channel into a controlled system block that can be tweaked to improve overall system performance. As a result, existing wireless channel modelling and performance evaluation approaches must be changed in order to evaluate the performance of IRS-enabled wireless communication systems in a variety of application scenarios. In this paper, the performance of 1RS assisted wireless systems under various application scenario such as 2.45 GHz, 5.9 GHz and 28 GHz has been evaluated with the help of an analytical model. The effect of spatial correlation in the SNR performance also has been evaluated.
