“…Additionally, there are studies in the literature to address RIS enabled PNC schemes. [23] introduced a dual-hop multicast transmission scheme employing PNC, featuring two source nodes and two destination nodes equipped with a single antenna. The authors demonstrated that the presence of the RIS significantly enhances the performance of the PNC scheme.…”

Reconfigurable intelligent surfaces (RISs) have been developed to exploit the stochastic characteristics of the propagation environment. On the other hand, the integration of wireless physical network coding (PNC) and multiple antennas yields notable enhancements in system performance. This paper presents a multi-user system, employing RIS enabled PNC alongside multiple antennas to minimize both latency and error probability. Our aim is to establish reliable communication between the user pairs, which communicate through a base station (BS) via RIS. Therefore, the reflecting coefficients including both phases and amplitudes of the RISs are optimized by using the alternating direction method of multipliers (ADMM) algorithm for both single and multiple RIS cases. Extensive results are presented to compare the proposed algorithm with random phase shift, network coding (NC) and the search algorithm to illustrate the superiority of the proposed method.
