description: The subject of the graduate qualification work is âSelection of the analysis interval for algorithm with decision feedback to improve the BER performance of M-ary FTN signalsâ. The given work is devoted to improving the BER performance of M-ary Faster than Nyquist (FTN) signals by optimizing the analysis interval for the detection algorithm with decision feedback. During the study, the methods of processing M-ary FTN signals were considered. Also, a simulation model based on the element-by-element detection algorithm and the decision feedback detection algorithm was developed. Matlab software has been applied for the simulation modeling. Based on the obtained results, the optimal analysis interval and the feedback depth for the studied signals were obtained, and a confidence interval for the probability of a bit error was additionally calculated. In addition, the energy gains provided by the optimal analysis interval in decision feedback detection algorithm were found for M-PSK and M-QAM. It is shown that the higher the level of intersymbol interference, the higher energy gain due to application of optimal analysis interval in decision feedback detection algorithm can be obtained. Open educational resources and programs for searching and analyzing information were used. MATLAB software is applied.
