Modernization of DVB-S2 Standard Using Signal-Code Constructions Based on Amplitude Modulation of Many Components

Horbatyi Ivan, Yashchyshyn Yevhen

International Journal of Electronics and Telecommunications

2020

Vol. 66, No. 2

315--320

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 signal-code constructions based on 8PSK and APSK.

Investigation of influence of parameters of the digital telecommunication system on its efficiency

Bobalo Yuriy, Horbatyi Ivan, Kiselychnyk Myroslav

Przegląd Elektrotechniczny
