In this paper, we present the performance analysis of asymmetric dual-hop\nRF/FSO system with multiple relays. The RF channels follow the correlated\nRayleigh fading while the optical links are subject to the Gamma-Gamma fading.\nTo select the candidate relay to forward the communication, we assume Partial\nRelay Selection (PRS) with outdated Channel State Information (CSI). Unlike the\nvast majority of work in this area, we introduce the impairments to the relays\nand the destination. We will propose three impairment models called Soft\nEnvelope Limiter (SEL), Traveling Wave Tube Amplifier (TWTA) and IQ Imbalance\nin order to compare the resilience of our system with the RF one against the\nhardware impairments. Closed-from of the outage probability (OP) is derived in\nterms of Meijer's G function as well as the upper bound of the ergodic capacity\n(EC). The Bit Error Rate (BER) and the exact EC are evaluated numerically.\nFinally, analytical and numerical results are presented and validated by Monte\nCarlo simulation.\n
