摘要：

The recent advent of simultaneous refracting and reflecting reconfigurable intelligent surface (STAR-RIS) has paved the way for next generation wireless technology by enhancing the quality of the signal with wider coverage area connectivity. In this work, we propose a novel STAR-RIS assisted full duplex (FD) wireless communication system where a FD base station (BS) communicates with an uplink user and a downlink user simultaneously with the aid of a STAR-RIS. First, we derive the probability density function (PDF) of the uplink and downlink signal to interference plus noise ratio (SINR). Using the derived PDF, we analyze the system performance and derive analytical closed-form expressions for the outage probability and achievable throughput for both the uplink and downlink communication. Finally, we validate the accuracy of the derived analytical expressions using Monte-Carlo simulations and show that the use of the STAR-RIS provides a significantly improved performance compared to the conventional RIS.
