“…The error probability performance analysis of systems subjected to HWIs has recently received few attentions [30]- [33]. In [30], Windisch and Fettweis quantified the impact of the receiver I/Q imbalance in terms of closed-form error probability.…”

“…In [32], Krishnan et al derived the SEP for systems suffering from Gaussian phase error. In [33], Bouhlel et al analyzed the pairwise error probability (PEP) over correlated Rayleigh and Ricean fading channel and incorporated both imperfect channel state information and additive hardware distortions. To the best of the author's knowledge, there is no substantial research that considers the aggregate effect of HWIs at both the transmitter and the receiver on the error probability performance.…”

“…In [36], the authors studied the performance of a multiuser communication system in rank-1 Rician fading channels, assumed both ICSI and transceiver HIs. The performance evaluation of orthogonal frequency division multiplexing with index modulation (OFDM-IM) under channel estimation error and HIs was investigated in [37]. In [34], Solanki et al analyzed joint impact of HIs and channel estimation error on OP of spectrum sharing DF multiple-relay networks, where the reactive relay selection was adopted.…”

In this paper, we investigate the performance of dual-hop (DH) decode-and-forward (DF) multi-relay networks, for which two practical deleterious factors are taken into account, namely hardware impairments (HIs) and imperfect channel state information (ICSI). The communication between the source and the destination is realized with the aid of DF multi-relays, where both hops are assumed to be independent but non-identically distributed α-µ fading. Aiming at improving the system performance, three representative relay selection strategies are considered, in which the best relay is selected according to the link quality of source-to-relay and/or relay-to-destination. To characterize the performance of the proposed strategies, two key performance metrics, namely outage probability (OP) and ergodic capacity (EC), are analyzed insightfully. We first derive closed-form expressions for both exact and asymptotic OPs. Utilizing the derived results, diversity orders achieved at the destinations are obtained. We demonstrate that the OPs of considered networks are limited by HIs and ICSI, and the diversity orders are zeros due to the presence of ICSI. Then, we study the ECs of the proposed relay selection schemes, and upper bounds for the EC and asymptotic expressions for the EC in the high signal-to-noise ratio (SNR) regime are derived. To obtain more insights, the affine expansions for the EC are involved by two metrics of high-SNR slope and high-SNR power offset. It is shown that there are rate ceilings for the EC due to HIs and ICSI, which result in zero high-SNR slopes and finite high-SNR power offsets.

BACKGROUND Cooperative communication has been identified as one of the core technologies in the current and future wireless communication networks [1]. With the aid of relays, we can potentially extend the coverage of wireless networks, improve quality of service (QoS) and reduce energy consumption [2]. For these reasons, it thus has attracted considerable interests from both The associate editor coordinating the review of this manuscript and approving it for publication was Rui Wang.

“…Besides, the performance of the underlay cognitive spatial modulation MIMO system with HW and channel imperfections has been examined in [27]. Finally, the authors in [28] studied the joint HW impairments with CEE and the study in [29] investigated the performance of energy harvesting two‐way relay systems with HW impairments.…”
