“…As the SI signal is much stronger than the signal of interest, the influence of the receiver non-idealities on SI signal will significantly increase the system's BER. The authors of [8] proved that IQ imbalance is also a critical issue for SMbased transmission. In [9] the performance of a SM system in presence of IQ imbalance has been studied via computer simulations and analytical derivations.…”

In this paper, we analyze, for the first time, the performance of a full-duplex system combined with spatial modulation technique in presence of the receiver non-idealities. IQ imbalance and phase noise are the two radio front-end mismatch factors that have been considered. The impact of the IQ imbalance on the bit error rate (BER) performance of the fullduplex spatial modulation (FDSM) system under different noise levels is investigated. An estimator has also been proposed for the self-interference cancellation (SIC) after the imperfect receiver. The results show that IQ imbalance does not significantly reduce system BER performance at low signal-to-noise ratios. Moreover, it is shown that the proposed estimator is able to maintain the system at an acceptable BER.

“…In this section, an optimal ML receiver is proposed for the presented CR wireless communication system, which has I/Q imbalance at STx/SRx and imperfect CSI at SRx. Considering the general signal model in (9), and the results in (12) and (13), and assuming that the I/Q imbalance parameters are known at the SRx, the joint probability density function (PDF) of the real part, y I , and the imaginary part, y Q , of the received signal can be written as [29], [30]…”

“…Indeed both inphase (I) and quadrature (Q) modulator and demodulator at the Tx and Rx may introduce phase and/or amplitude mismatch [22]. Additional harmful effects could degrade the system performance such as crosstalk and frequency interference [23][24][25]. Hence, taking into account IQI effects is a crucial factor for RIS effective design policies.…”

Reconfigurable intelligent surface (RIS) for wireless networks has emerged as a promising future transmission technique to create smart radio environments that improve the system performance by turning the wireless channel into an adjustable system block. However, transceivers come with various hardware impairments, such as phase noise and in-phase/quadrature-phase imbalance (IQI). Hence, for robust configuration of RIS-based communication under practical conditions, assuming the identical performance analysis when subject to IQI, will lead to inaccurate analysis. In this paper, the implementation of this novel transmission technique is thoroughly investigated under intensive realistic circumstances. For this purpose, based on the maximum likelihood (ML) detector, a novel analytical expression of average pairwise error probability under IQI is proposed and compared to the standard ML detector. Further, the proposed analytical approaches are confirmed by numerical simulations.
