| Abstract: | 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. |
