“…The use of the soft BER stopping rule is shown to be helpful to decrease the computational complexity with similar BER performance. In [46] the asymptotic BER performance of reconfigurable intelligent surfaces (RIS) model is mathematically derived and confirmed via Monte Carlo simulation. For the purpose of channel impairments, the proposed design in [47] for vehicle to everything (V2X) communication had become very effective for higher-order modulation with more than 85% improved BER and accuracy of mean-squared error (MSE) lesser than 10 −4 .…”

“…Attracted by the appealing advantages of RIS, most works focused on the phase shift matrix design with/without the transmit beamforming to achieve optimal performance and maximum reliability ( [1] and references therein). The influence of phase noise due to low-resolution quantization and imperfect channel estimation has also been investigated in [4]- [10]. In particular, a power scaling analysis in [8] showed that using 2 or 3-bit phase shifters is practically sufficient to achieve close-to-optimal performance.…”

Statistical characterization of the signal-to-noise ratio (SNR) of reconfigurable intelligent surface (RIS)-assisted communications in the presence of phase noise is an important open issue. In this letter, we exploit the concept of copula modeling to capture the non-standard dependence features that appear due to the presence of discrete phase noise. In particular, we consider the outage probability of RIS systems in Rayleigh fading channels and provide joint distributions to characterize the dependencies due to the use of finite resolution phase shifters at the RIS. Numerical assessments confirm the validity of closedform expressions of the outage probability and motivate the use of bivariate copula for further RIS studies.

“…For the case of Gaussian distributed channels and considering parameters such as the distances between devices and the number of LIS elements, Yang et al [15] derived closed-form expression for the secrecy outage probability (SOP) assuming that the LIS uses CSI to implement the phase shifting perfectly. In its turn, Trigui et al [16] assumed a more realistic model in which there are errors caused by phase quantization. By leveraging Fox's H transforms, they obtained exact SOP expression under the assumption that many reconfigurable elements of LIS and channels were distributed according to the Rayleigh distribution.…”

Large intelligent surfaces (LIS) are a new trend to achieve higher spectral efficiency and signal-to-noise ratio in mobile communications. For this reason, this paper proposes metrics to analyze the performance of systems with multiple antennas aided by LIS and derive the spectral efficiency, secrecy outage probability, and bit error probability in an environment with Nakagami-m distributed fading. In addition to an eavesdropper, there is a single-antenna user, an array of antennas at the transmitter side and the possibility of a direct link between transmitter and receiver. This study assumes that the LIS performs non-ideal phase cancellation leading to a residual phase error that follows a Von Mises distribution, and shows that the resulting channel can be accurately approximated by a Gamma distributed SNR whose parameters are analytically derived. From these formulas, it is possible to evaluate the effect of the strength of the line-of-sight link by varying the Nakagami parameter, m.
