Sažetak
This paper investigates the performance of reflective
intelligent surface (RIS)-assisted bi-directional full-duplex
(FD) systems considering hardware impairments (HIs), and selfinterference
(SI) under Nakagami-m fading. Unlike previous
research that assumes ideal hardware or Rayleigh fading, this
work derives closed-form expressions for outage probability,
asymptotic diversity, throughput, and energy efficiency. The
analysis employs a novel Gamma approximation, based on
moment-matching and a first-order Laguerre series expansion,
to accurately model Nakagami-m product channels. The derived
formulations allow efficient performance comparisons, including
RIS-assisted half-duplex (HD) systems with and without hardware
impairments. Numerical results reveal that using HIs/SI results
in error floors. Increasing the number of reflective elements
N, reduces the outage probability and enhances throughput
and energy efficiency. The Monte Carlo simulations validate the
analytical findings. Therefore, the proposed framework provides
valuable design insights into the trade-offs among transceiver
non-idealities, RIS size, and overall system robustness, serving
as a critical reference for designing energy-efficient, hardwareaware
RIS-assisted FD communication architectures in future
wireless networks.
