Abstract
- This article evaluates performance metrics in terms of outage probability (OP), throughput, and energy efficiency (EE) of the reconfigurable intelligent surface (RIS) assisted full-duplex (FD) wireless communication systems under the joint and separate effects of imperfect conditions such as residual transceiver hardware impairments (RTHIs) and residual self-interferences (SIs). More specifically, we derive the exact formulas of OP, throughput, and EE of the RSI-aided-FD systems with the joint effects of RTHIs and residual SIs. From the obtained expressions, it is easy to formulate the formulas of the relevant systems such as RIS-aided-FD systems without RTHIs and RIS-aided-half-duplex (HD) systems without and with RTHIs. Numerical illustrations clarify the huge impacts of RTHIs and residual SIs on the OP, throughput, and EE of the RIS-aided-FD systems, especially in the high data rate. In this situation, utilizing a large number of reflecting elements (REs) can dramatically enhance the OP, throughput, and EE performance of the RIS-aided-FD systems with RTHIs and residual SIs. Finally, the derived formulas are validated by using Monte-Carlo simulations. [ABSTRACT FROM AUTHOR]
