Performance Analysis of ASTARS-Assisted Uplink Communication Networks

Active simultaneously transmitting and reflecting reconfigurable intelligent surface (ASTARS) warrants in-depth research to enhance the reliability and efficiency of sixth-generation wireless communication. This paper investigates the performance of ASTARS-assisted uplink communication networks. We derive new closed-form expressions for the outage probability, considering both perfect and imperfect successive interference cancellation scenarios, and subsequently calculate the throughput and energy efficiency. Numerical results indicate that ASTARS-assisted networks significantly outperform passive counterpart networks.
