Currently, the types of signal modulation in satellite communication networks must meet the requirements of high noise immunity and spectral efficiency with certain insensitivity to the nonlinearity of the path.

The purpose of this work is to study the spectral and energy efficiency of the modulation types of data transmission standards, and how the nonlinearity of the radio path affects the noise immunity of modulation in satellite communication systems. Signal constellations of modulation by peak factor are compared.

A comparative analysis of the spectral and energy efficiency of the types of signal modulation regulated by the standards of digital satellite video broadcasting DVB-S and DVB-S2, which could be used in satellite communication systems, was carried out.

It is shown that in satellite communication networks it is reasonable to use the types of phase modulation BPSK, QPSK and 8PSK for lines with low energy, and for lines with higher energy – amplitude-phase modulation 16APSK and 32APSK in order to save frequency resource.
