Abstract:
Status of power frequency communication research is analyzed in this paper. The signal definition and modulation are introduced. Influence from 50Hz electric power wave with its harmonious wave is cancelled through the adaptive notch filter. To demodulate the signal from substation, modulated wave were sampled and recorded in memory for matched filter and power spectrum analyses, The output of matched filter is imported for soft judgment decoder.
Keywords:over transformer power frequency communication adaptive notch filter matched filter soft judgment decoder
