The paper shows the opportunity of significant bitrates increase in satellite broadcasting system DVB-S2X for simultaneous transmission of two services with Layered Division Multiplexing (LDM). A simulation MATLAB model was developed for this research. The model includes main blocks for generating and receiving the signals both for linear channels with additive white gaussian noise and for non-linear channels taking into account amplitude characteristics of satellite transmitting equipment. Several use cases were considered for transmission of different broadcast and communication services with different requirements for signal-to-noise ratio. It is shown that for considered scenarios the application of LDM provides the increase of bitrates for more than 24% in comparison with the use of traditional Time Division Multiplexing (TDM).
