“…It indicates that the MAUR decreases with k B and k s . This conclusion is also consistent with the SINR formula in (13). Furthermore, when k B , k s are set to 0, the result is identical to the situation when hardware impairments are not considered.…”

“…Besides the transceiver hardware impairment, the authors of [12] further considered the impact of the phase noise at the RIS and derived the closedform data rate expression, based on which the genetic algorithm was adopted to solve the phase shift optimization problem. In [13], the RIS-aided communication system for serving a mobile user was studied, and the authors proposed an interesting algorithm to predict the positions of the user under HWI. In [14], the authors analyzed the outage performance for RIS-aided non-orthogonal multiple access systems with HWI, where both near-field and far-field users were considered.…”

“…It is shown that the spectral efficiency (SE) is limited due to HWI even when the numbers of transceiver antennas and RIS elements grow infinitely large, which is in contrast with the conventional case with ideal hardware. Furthermore, we [19] revealed that HWI on the RIS has no impact on Doppler shift and spread, but would increase delay spread.…”

“…Due to the importance of hardware failures, the baseband complex received signal from a RIS element has been modeled in [10], considering faulty reflecting elements of RIS. Thus, in order to design reliable RIS based networks in practical environments, it is essential to develop resource allocation schemes aware of RIS array failures.…”
