摘要
介绍了一种基于统计方法得出的低压电力线载波信道模型 ,并分析了OFDM技术和扩频通信各自对于低压电力线通信的优缺点。最后给出了这两种调制方式基于本文信道模型的仿真结果。
Introduce 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.Discuss two modulation technologies:OFDM and Spread Spectrum.Present their principle and implementing method in high data rate power line communication.Conclude that OFDM is much better for power line communication.
