ABSTRACT:
A method for transmitting data via the power system line of a power supply system by carrier frequency modulation, wherein an improvement in the reliability of transmission is achieved by transmitting the same information several times in succession (time diversity) of different carrier frequencies (frequency diversity). Additional coding of the data by a "forward error correction code" results in further improvement.
