摘　　要：本文论述了基于扩频通讯技术的低压电力线载波通讯系统的算法设计、硬件实现和验证结果。作为低压电力线载波扩频通讯芯片的FPGA验证系统,本系统重点研究了如何用成熟的MCU技术和较少的硬件资源将复杂的扩频通讯技术应用于恶劣的低压电力线通讯环境中,以获得高可靠性的长距离数据通讯。本文论述的系统已经通过现场验证,收到了良好的效果。The theoretical principle and hardware configuration of a spread-spectrum communication system over power lines is discussed. A FPGA module for the spread-spectrum communication over power lines is built to test the prototype of a DS-Spread-Spectrum communication system for the remote user metering of public utility companies. Key issues of design are focussed on how to apply the complex spread-spectrum technology with simple hardware and how to attain reliable communication over long distance power lines in such highly unstable communication environment. The experiment system has been built and passed field test with satisfactory results.
