摘要
低压电力线载波通信将会扩大现有通信网的覆盖范围,产生极大的经济效益;介绍了电力线载波通信技术,分析了低压配电网对信号传输衰减大、干扰强、阻抗变化复杂的信道特性;着重对扩频通信技术在电力线载波通信中的应用进行了研究;提出了一种电力线扩频通信方案.
The paper introduces the technology of power line communication (PLC) and analyzes the transmission characteristics of low voltage power line system. Where signal attenuation, strong disturbance and complex variation of impedance exist. The paper emphases the research of spread spectrum communication applying to the PLC system.
