“…A considerable number of publications are devoted to the issue of improvement the quality and efficiency indicators of satellite video broadcast systems and wireless telecommunication systems. In particular, in [1] the possibility of improving the quality and technical efficiency of the information transmission in the cooperative digital video broadcast systems based on DVB-SH (Digital Video Broadcasting -Satellite Services to Handhelds) standard by rotate the signal constellation of the quadrature phase shift keying (QPSK) signal was investigated. A quality improvement (a bit error rate decreasing) or increasing frequency efficiency of the system by more than 1 dB at This work was supported by Ministry of Education and Science of Ukraine under project No 0118U000261.…”

It is proposed to modernize the DVB-S2 standard by using AMMC (amplitude modulation of many components) signals instead of 8PSK (8-phase shift keying) and APSK (amplitude-phase shift keying) signals, and to modernize the DVB-S2 standard equipment by using the AMMC modulator and AMMC demodulator. Usage of AMMC makes it possible to reduce the symbol error rate in communication channel up to 52 times. The satellite digital video broadcast systems that apply signal-code constructions based on AMMC are characterized by a higher energy efficiency from 1 to 2.6 dB compared with signalcode constructions based on 8PSK and APSK.
