description: The purpose of the work is to evaluate the effectiveness of a probabilistic method for reducing the crest factor of FTN signals generated according to the DVB-S2, DVB-S2X standards. In the course of this work, methods for reducing the crest factor for FTN signals were considered. A simulation model was created based on the lower layer of the scrambler from the DVB-S2, DVB-S2X standards. MATLAB software was used to model the developed simulation model. Based on the results obtained, the gain from using the probabilistic method of reducing the crest factor was assessed according to the level of the complementary cumulative distribution curve equal to 10â3. As a result, by increasing the symbol rate by 25% and using the probabilistic method of reducing the crest factor with S=16, the gain in crest factor is up to 1.45 dB for M=256 compared to the case of orthogonal transmission for the DVB-S2X standard. The scope of this research is satellite television broadcasting systems with high crest factor characteristics. Open educational resources and programs for searching and analyzing information were used. MATLAB software was used.
