description: Topic of the graduation thesis: "Increasing the efficiency of the information transmission system based on optimal FTN signals by taking into account the multipath nature of the transmission channel". The object of research in this work is the optimal FTN signals in multipath conditions. The aim of the work is to analyze the possibility of improving the efficiency of the information transmission system based on optimal FTN signals by taking into account the multipath nature of the transmission channel. In the work, a technique for solving the optimization problem was considered and evaluated, taking into account the multipath nature of the transmission channel. This technique can be used to improve the efficiency of production automation for solutions of the "mid-end" class, industrial mid-end wearable applications (IM-EWA). The ability to adjust the spectral characteristics will allow a flexible approach to complex industrial conditions for information transmission. Various existing methods of reducing the influence of multipath propagation were considered, as well as their shortcomings. The advantage of optimal signals over other methods of dealing with the consequences of multipath propagation is that already at the stage of signal synthesis it is possible to obtain a potential improvement in reception without complicating it. The optimization problem of searching for the envelope of a random sequence of single-frequency signals with a given rate of decay of the out-of-band radiation level under restrictions on the BER performance of the reception, as well as its numerical and analytical solution, has been posed and considered. A solution to the optimization problem posed is proposed by expanding the desired envelope into a bounded Fourier 7 series, when the variational problem is reduced to finding the minimum of a function of many variables in the presence of constraint equations. As a restriction on the BER performance of reception, a restriction in the form of an inequality is considered. A simulation model has been developed that makes it possible to determine the BER performance of single-frequency signal reception and signal characteristics. A multipath simulator is described, and a scenario for it with one transmitter and three receivers is formulated. An equalizer was calculated to improve the quality of signal reception, taking into account multipath. Data from the output of the multipath simulator was also obtained and analyzed. Examples of solving the optimization problem for different cases, taking into account the multipath transmission channel, are considered. The curves of BER performance of single-frequency signals are constructed for different receivers with different optimal envelopes. The effect of different time shifts on the BER performance was considered when using an envelope with a restriction on BER performance, taking into account the shift T/2. By using such a technique, it is potentially possible to achieve a gain in BER performance without additional resource costs. The scope of the method is also defined. The influence of the equalizer implemented according to the Zero Forcing algorithm was evaluated. The further development of the method is considered taking into account several times shifts in the optimization problem.
