METHOD OF DIGITAL MODULATION Russian patent published in 2011 - IPC H04L27/18 

FIELD: information technologies.

SUBSTANCE: serially operations of complex signal generation are performed, pulses of positive and negative signal edges are identified, being formed with the help of clock pulses, logical summation of produced edge pulses is carried out, phase function counts are carried out, falling for a single signal edge, partial phase trajectory of a signal is entered into the memory in the form of vector rotation coordinates within the limits of a half of a unit circumference of a complex plane, components of a complex signal are formed, their digital-to-analogue conversion is carried out, two carrier oscillations are smoothened, mixed with modulating components, two modulated oscillations are combined, and radio signals are sent.

EFFECT: reduction of spectral side tabs and narrowing of energy spectrum.
