description: The subject of the graduate qualification work is âDoppler effect in SEFDM signalsâ. As a result of the study, a simulation model was implemented, including the formation of an SEFDM signal, a block simulating the Doppler effect and a block compensating for this effect. At the end of the simulation model is a block that calculates the errors that occur during signal transmission. This value will show the influence of the Doppler effect on the signal. In addition, the compensation methods themselves were implemented and a quantitative assessment was made of the work of the Doppler effect compensation methods. After obtaining numerical values, a comparison was made between the methods for various objects, each of which moves at its own speed. It was evaluated which of the methods is more suitable for specific situations. The analysis of the methods themselves was carried out and strengths and weaknesses were identified in comparison with other methods. Also, the methods themselves have undergone systematization to some extent. An analysis was made of the effect of an error in the compensation method on the performance of the methods. Numerical values ââare obtained depending on the magnitude of the error. A graph has been constructed to demonstrate this dependence.
