摘　　要：电力线通信收发器主要由物理层、介质访问层和逻辑链路层3部分构成,其中物理层是电力线通信收发器系统最基础和最关键的部分之一,其功能主要是把信号调制成为可以传输的信息,并解调发射端传输的信息,提高通信系统的抗干扰性和稳定性。为了更加全面和深入地了解电力线通信系统标准中物理层性能上的特点,文章对目前国际上主流电力线通信系统标准的物理层技术进行了介绍,重点对窄带电力线通信相关标准物理层技术进行了总结、分析。Power line communication transceiver is mainly composed of three parts, including the physical layer, medium access layer and the logical link layer, the physical layer is one of the most basic and critical parts of power line communication, its main function is to modulate input signal to information that can be transmitted and demodulation of transmission information from transmitter as to improve the anti-interference and stability of the communication system. For more comprehensive and in-depth understanding of the physical layer properties of the power line communication system, the physical layer technologies of the current international mainstream power line communication system standards are introduced in the paper, and the physical layer technologies of narrowband power line communication related standard are mainly summarized and analyzed.
