Abstract (en)
[origin: WO0131868A1] A signal of any physical form corresponding to an information character of an encoding alphabet, is transmitted as an analog waveform defining a symbol, the waveform being cyclical at the symbol rate, to a communication channel and then the signal when received by a receiver is converted to groups of pulses separated by silences, wherein each group of pulses maps to a count corresponding to a character of the encoding alphabet. The groups of pulses are separated by silences of arbitrary duration which are greater than the time between individual pulses. The pulses have a pulse rate greater than the frequency of the symbol. The system permits but does not require communication of relatively narrow bandwidth signals.
