  In this paper, we study a dual-hop mixed power line communication and
radio-frequency communication (PLC/RF) system, where the connection between the
PLC link and the RF link is made by a decode-and-forward (DF) or
amplify-and-forward (AF) relay. Assume that the PLC channel is affected by both
additive background noise and impulsive noise suffers from Log-normal fading,
while the RF link undergoes Rician fading. Based on this model, analytical
expressions of the outage probability (OP), average bit error rate (BER), and
the average channel capacity (ACC) are derived. Furthermore, an asymptotic
analysis for the OP and average BER, as well as an upper bound expression for
the ACC are presented. At last, numerical results are developed to validate our
analytical results, and in-depth discussions are conducted.
