级联多线PLC/MIMO-RF通信系统性能分析
On Performance Characterization of Cascaded Multiwire-PLC/MIMO-RF Communication System
摘要：
射频（RF）系统的灵活性和电力电缆的无处不在潜在地使得级联电力线通信（PLC）/RF系统在广覆盖和高速传输方面成为高效且具有成本效益的解决方案。这封信提出了一个机会解码和转发（DF）为基础的多线/RF中继系统，利用这两种技术的优点。相应地选择中断概率、出错率和系统信道容量来分析所提出的系统的特性，这些特性以封闭形式的表达式导出，并通过Monte-Carlo仿真进行验证。可以观察到，我们提出的系统在覆盖范围和数据率方面优于仅无线系统，特别是当发射机和接收机对之间存在非视距（NLoS）连接时。
英文摘要：
The flexibility of radio frequency (RF) systems and the omnipresence of power cables potentially make the cascaded power line communication (PLC)/RF system an efficient and cost-effective solution in terms of wide coverage and high-speed transmission. This letter proposes an opportunistic decode-and-forward (DF)-based multi-wire/RF relaying system to exploit the advantages of both techniques. The outage probability, bit error rate, and system channel capacity are correspondingly chosen to analyze the properties of the proposed system, which are derived in closed-form expressions and validated via Monte-Carlo simulations. One can observe that our proposed system outperforms the wireless-only system in terms of coverage and data rate, especially when there exists a non-line-of-sight (NLoS) connection between the transmitter and receiver pair.
