Abstract :
Construction methods for a pulse-position multifrequency code are considered. This code eliminates undesirable frequency combinations between adjacent codewords. Optional methods of dividing the frequency scale for low-speed multifrequency data transmission systems are discussed. This allows a choice of frequency scale depending upon the nonlinearity of the channel.
