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.

双跳混合PLC/RF通信系统的性能分析

在本文中，我们研究了一个双跳混合电力线通信和射频通信 (PLC/RF) 系统，其中 PLC 链路和 RF 链路之间的连接是通过解码转发 (DF) 或放大转发 (AF) 中继。假设 PLC 信道受到加性背景噪声和脉冲噪声的影响，受到对数正态衰落的影响，而 RF 链路则经历 Rician 衰落。基于该模型，推导出中断概率（OP）、平均误码率（BER）和平均信道容量（ACC）的解析表达式。此外，还给出了 OP 和平均 BER 的渐近分析，以及 ACC 的上限表达式。最后，开发数值结果来验证我们的分析结果，并进行了深入的讨论。
