Abstract
Reconfigurable Intelligent Surface (RIS) is a transformative technology which can enhance the performance of the ubiquitous wireless networks and achieve better signal quality with the aide of multiple reflecting surfaces. In this work, an analytical framework of a RIS-aided full duplex (FD) communication network consisting of a FD-access point (AP) that communicates with an uplink and a down-link users simultaneously is provided. In particular, we analyze the performance of the considered system by deriving analytical expressions of outage probability for both uplink and downlink transmissions. Further, the accuracy of the derived expressions is validated using simulation results. Finally, from the comparative analysis, it is shown that the RIS outperforms the system without RIS providing remarkable improvement in the outage probability.
