description: As a result of the study, a simulation model of information transfer using FTN signals was developed for the coherent element-by-element reception algorithm, the algorithm with decision feedback, the algorithm "brute force". Noise immunity curves were obtained for different signal acquisition algorithms and different envelopes. The computational complexity of the algorithms was evaluated, as well as the efficiency of the algorithms under different envelope parameters with high-frequency filling and BPSK modulation. The study may be of interest in the implementation of communication systems using FTN signals. These systems allow you to transmit more information per unit of time, increasing the bandwidth of the communication channel without increasing the width of the signal spectrum. Open educational resources and programs of information search and analysis were used. Matlab automation (automated) development tools were used. Matlab software was used (tested).
