摘要

这项工作旨在分析传输功率和频率带宽对家庭合作电力线通信(PLC)的影响，基于测量活动提供的信道估计。考虑厄米对称正交频分复用方案最大数据速率的封闭表达式，从中继节点位于源节点和目的节点中间的单中继模型角度研究了基于协作的家用PLC信道。对放大转发(AF)和解码转发(DF)协议以及等增益组合(EGC)、选择组合(SC)和最大比值组合(MRC)技术进行了分析。数值结果表明，与直接链路相比，频率带宽的增加和/或传输功率的降低会带来显著的数据速率增益。

The influence of transmission power and frequency bandwidth on in-home cooperative power line communication

This work aims to analyze the influence of transmission power and frequency bandwidth on in-home cooperative power line communication (PLC) based on channel estimates provided by a measurement campaign. We investigate in-home PLC channels based on cooperation from a single relay model perspective in which the relay node is located in the middle between source and destination nodes by considering closed-form expressions of the maximum data rate of hermitian symmetric orthogonal frequency division multiplexing scheme. The analysis is carried out over the amplify-and-forward (AF) and decode-and-forward (DF) protocols, together with the equal gain combining (EGC), selecting combining (SC) and maximal ratio combining (MRC) techniques. Numerical results show that an increase in frequency bandwidth and/or a decrease in transmission power introduce notable data-rate gains compared to direct link.
