FIELD: fast and uninterrupted transmission of data over power supply network with any values of voltage. SUBSTANCE: technical result f invention lies in use of method of modulation of many carriers to diminish complex effect of noise manifested in signal distortion, in frequency-selective fading or attenuation of signal, in pulse noise. Intensity of appearance of errors can be markedly decreased as result of combination of modulation of many carriers by specially adapted data interleaver and by noise-immune coding and speed of transmission of data can explicitly raised to values above 2.0 kbit/s. EFFECT: diminished complex effect of noise. 13 cl, 4 dwg
