Abstract: A communication signalling system containing a control unit receiving input data from one source and a reference signal from another source, a modulator receiving an input from the control unit, and a plurality of tones from a separate source, the phase of each of the tones received by the modulator being modulated in response to the input received from the control unit, an adder which receives the modulated signals from the modulator and converts the signals into a composite signal which is then sent to a latch unit which also receives a signal from a symbol interval clock, the latch unit sending a composite signal to a transmitter for transmission during a given symbol interval, an antenna and receiver detector unit for receiving the signal being transmitted, the signal being forwarded to a filter and correspondence circuit which breaks out the individual modulated signals comprising the original frequency, the modulating phase, and a random unknown interference, the individual signals being applied to and
