description: The object of study is signals based on RRC pulses transmitted at an increased rate and at the Nyquist rate. The purpose of this work is to determine the signal structures that are optimal from the point of view of maximizing energy efficiency when using computationally simple reception algorithms under conditions of equal spectral efficiency. As a result of the study, a simulation model was built in the MATLAB environment to evaluate the noise immunity of reception and the PAPR of a random sequence of FTN signals and Nyquist signals based on RRC pulses. Based on the developed model, FTN signals and Nyquist signals were compared under conditions of the same spectral efficiency. The parameters of signal structures providing energy gain under given conditions are determined. Open educational resources and programs for searching and analyzing information were used. MATLAB software is applied.
