description: The subject of the graduate qualification work is - spectrally efficient frequency division multiplexing. The purpose of the work is to reduce the computational complexity of receiving SEFDM signals in fading channels with an ideal channel estimate. The work was the application of decision feedback demodulation algorithms for receiving SEFDM signals in fading channels. Goals and tasks performed in the work. In this work, decision feedback demodulation algorithms were used for demodulating SEFDM signals. To equalize a fading SEFDM signal, one simple method is the ZF equalizer. The results were an analysis of the noise immunity of receiving SEFDM signals in fading channels using decision feedback demodulation algorithms and Zero-Forcing equalizer with an ideal channel estimate. The parameters are implemented in the model: the number of used subcarriers, the compression ratio, the length of the guard interval, the number of Fourier transform points and the EPA, EVA, ETU channels. Simulation of SEFDM signals in the MATLAB environment has been performed. Results are obtained and conclusions are drawn. Open educational resources and programs for searching and analyzing information were used. MATLAB (automated) development tools were used. Applied (tested) software: MATLAB.
