| Abstract: | This paper introduces a power line channel model combined with an AWGN filter and a multi-path model, which is analyzed and derived from a great number of measurements, discusses two modulation technologies: OFDM and spread spectrum, presents their principle and implementing method in high data rate power line communication. It concludes that OFDM is much better for power line communication. |
