description: This paper examines FTN signals that are proposed for use in the latest information transmission systems instead of classical technologies such as, for example, OFDM. These signals are spectral-efficient, but existing works practically do not consider the main disadvantage of OFDM technology - the large value of the peak-factor and methods to reduce it. In addition, the proposed versions of such signals can often have a comparable peak-factor, which can make such signals inapplicable in practice. In this work, a technique has been developed for optimizing the envelope of FTN signals with a peak-factor limitation at different symbol rates. A variant of a numerical solution is proposed using the expansion of the envelope in a Fourier series. FTN signal envelopes are obtained for various peak-factor constraints for wide symbol rates. The boundaries of application of the proposed agreement are analyzed. Terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized software and mathematics were used MATLAB.
