description: The given work is devoted to synthesize optimal pulses for FTN signals and study their properties. As a result of the study, a simulation model was developed, a software and hardware platform for testing optimal impulses, and the optimization problem for providing a given decay rate was modified. Optimal pulses were synthesized, their noise immunity and crest factor were investigated. An experiment was carried out on the emission of FTN signals using optimal pulses. As results, the dependence of the energy loss on the correlation coefficient, the optimal pulse shapes and their spectra, the noise immunity curves corresponding to them, and the experimental noise immunity curve were obtained. Based on the results, it became clear that the energy loss and the correlation coefficient have a direct relationship, using which it is possible to synthesize pulses that provide almost win-win reception at an increased symbol rate. With an increase in the symbol rate, it is necessary to take into account the correlation coefficient not only with the adjacent, but also with subsequent pulses, in order to maintain the same noise immunity. Open educational resources and programs for searching and analyzing information were used. MATLAB automated development tools were used. The SDR# software was used to receive and create a record of signal samples.
