description: The object of study is M-ary FTN-signals. The aim is to increase the noise immunity of receiving M-ary FTN-signals using coordinate interleaving. In the course of the work, algorithms for generating and receiving binary and M-ary FTN-signals based on RRC pulses were investigated. In addition, a simulation model of the algorithm for receiving and generating FTN-signals for the receiving algorithm using coordinate interleaving (CI) was developed in the MATLAB environment. The results of the simulation are noise immunity curves, in which it can be seen that for the CI-FTN algorithm with overestimation for binary and M-ary FTN-signals, the results turned out to be almost identical to the noise immunity curve for signals without interference. The coordinated interleaving reception algorithm for M-PAM modulation has an energy penalty over the decision feedback reception algorithm taking into account subsequent symbols for M2-QAM modulation in the range from 0.3 dB to 4 dB. Also, the coordinated interleaving reception algorithm has a higher computational complexity. However, introducing an overestimation of subsequent symbols improves the results for the coordinate interleaving method by about 4 dB. Open educational resources and programs for searching and analyzing information were used. MATLAB software is applied.
