先进的通信技术使电力线通信（PLC）通道成为一种传输介质，能够在经典的室内电线上传输高速数字数据。用于互联网、语音和数据业务的PLC系统的开发需要基于测量的主网传输特性模型，适合通过仿真进行性能分析。本文提出了只用一个参数描述电力网复杂传递函数的幅值和相位的确定性模型。首先，实现了PLC信道分类，并提出了按类别划分的平均幅度和相位信道模型。其次，介绍了PLC信道的多径特性。建立了基于统计的信道幅度发生器，并提出了基于群延迟的相位模型。
Advanced communication technologies have allowed the power-line-communication (PLC) channel to be a transmission medium that enables the transfer of high-speed digital data over the classical indoor electrical wires. The development of PLC systems for Internet, voice, and data services requires measurement-based models of the transfer characteristics of the mains network suitable for performance analysis by simulation. This paper presents a deterministic model describing the magnitude and phase of complex transfer functions of power-line networks using only one parameter. First, a PLC channel classification is realized, and an average magnitude and phase channel model by class is proposed. Second, the multipath characteristic of PLC channels is introduced. A statistical-based channel magnitude generator is built, and a group delay-based phase model is suggested.
