FIELD: communication technology.
SUBSTANCE: invention relates to the field of communication. The expected result is achieved due to the fact that in order to transmit a signal using a carrier frequency with zero side bands directly, (1020) modulating signals are received and (1040) modulated sinusoidal carrier waves with zero side bands are generated, including one or more cycles of sinusoidal waves at the carrier frequency having one or more parameters set, defined for a full cycle at the beginning of each cycle of sinusoidal waves at one or more zero voltage intersection points in accordance with one or more values of one or more modulating signals. One or more set parameters to be changed are selected from a group of amplitudes, frequencies, phases, time periods and their combinations.
EFFECT: reducing the minimum bandwidth of the spectrum for each RF modulating signal.
