Abstract

Method of data transmission in which, independently of the transmission network, the sending terminal sends a signal, composed of a set of elementary signals each of which is determined by each data element and in which the receiving terminal reconstitutes a signal whose data can be extracted, characterized in that (by designating t the elementary data duration) the elementary signal ss sent by the transmitting terminal is the same signal as that resulting from the double-band modulation of a carrier f1 by the signal (see formula) and because in the receiver terminal the received signal is demodulated by a frequency f that returns to give ss when it is modulated by (see formula) (Machine-translation by Google Translate, not legally binding)
