DEVICE FOR GENERATING OPTIMAL SPECTRALLY EFFICIENT SIGNALS WITH PHASE MODULATION Russian patent published in 2025 - IPC H04B1/02 

FIELD: communication technique.

SUBSTANCE: invention relates to communication engineering, in particular, can be used in systems for transmitting data over a radio channel to generate spectrum-limited signals with phase modulation and constant amplitude level of signals. In the device for generating optimal spectrally efficient signals with phase modulation, a first quadrature component is created, for the formation of which the phase components of the signal are added, and a second quadrature component, for the formation of which the amplitude components of the signal are added, wherein the signals of the two quadrature components, obtained from the first and second quadrature component generators, have an increased duration and a smoothed shape.

EFFECT: increased volume of transmitted information in the allocated frequency band at controlled level of out-of-band emissions and peak-factor of radiated oscillations when using signals with phase modulation.
