description: The object of the graduate qualification work is a satellite communication channel with non-linear distortions due to the characteristics of the power amplifier. The purpose of the work is to increase the information transfer rate when using the DVB-S2(X) standard with TDM (Time Division Multiplexing) by using LDM (Layered Division Multiplexing) technology in the conditions of an AWGN channel and a power amplifier with nonlinear phase and amplitude characteristics at using signal predistortion. This given work is devoted to the study of the possibility of increasing the information transfer rate in the DVB-S2(X) standard relative to TDM by using LDM technology. When using TDM technology, the channels are separated by time, and in LDM by power level. Three scenarios were considered to compare TDM and LDM technologies. Also, three models are considered for approximating the characteristics of amplifiers: Saleh, Ghorbani, Rapp. In addition, signal predistortion has been added as a method of compensating for non-linear distortion caused by the power amplifier. In MATLAB, a simulation model of the physical layer of the DVB-S2(X) standard was implemented with a nonlinear power amplifier, signal predistortion and with the introduction of LDM. It is shown that for the first scenario, the use of LDM technology provides a gain in information transfer rate compared to TDM technology, equal to 96.3%, for the second - 28.6%, and in the third scenario, LDM technology loses by 6.5%. It has also been shown that regardless of the type of power amplifier model chosen, the results remain constant.
