This work is devoted to the analysis of modern research in the development of systems for transmitting and receiving information based on FTN signals and the creation of a simulation model based on them. Faster than Nyquist (FTN) signaling is a non-orthogonal transmission scheme in which pulses appear faster than the rate known from the Nyquist criterion. FTN signals provide higher data rates than Nyquist signals but introduce intersymbol interference due to violation of Nyquist's theorem. This paper examines the performance of the FTN system in terms of various reception algorithms, bit error rate (BER), peak to average power ratio (PAPR), spectral efficiency. The results obtained are compared with the Nyquist signals. The simulation results confirm that the FTN signaling system has a higher spectral efficiency than the Nyquist signaling system. In addition, the FTN system has advantages in terms of BER using a pulse shaping filter. A measure of the interaction of neighboring pulses of the transmitted signal sequence is shown by calculating the correlation coefficient for various symbol rates and limiting the crest factor to 4 dB. At the end of the work, the optimal parameters for the most efficient operation of the simulation model are highlighted. The research results were obtained by the Monte Carlo method. |
