摘要

In this work, we analyze the performance of a reconfigurable intelligent surface (RIS) assisted radio frequency (RF) system in smart grid application. In a smart grid, the smart meter (SM) plays an important role in communication between the smart devices and the utility control centre (UCC). The UCC can communicate using the RIS assisted communication link to the SM and the SM interact with the smart devices with the communication link based RF communication using the RQAM modulation scheme. Based on the system model, a closed-form expression for the average symbol error rate (ASER) is derived and analyzed by varying the various parameters like the number of reflector in the RIS, traffic intensity, quadrature to in-phase decision distance ratio, and the total number of devices.
