description: In MatLab, a model for transmitting and receiving Multicarrier faster-than-Nyquist (MFTN) signals has been developed. To reduce intersymbol interference, a filter of the root type from the raised cosine is used. By simulation, the noise-immunity curves of MFTN signals and signal spectra for a system with a linear characteristic for all signal values ââare obtained. The peak factor of the MFTN signals is estimated depending on the filter smoothing coefficients and the time overlap. The behavior of these signals in the limited dynamic range of a power amplifier is investigated. To assess the energy efficiency, the dependence of the energy loss compared to the ideal case on the magnitude of the offset of the operating point of the amplifier for different signal parameters is obtained. As a result of the analysis of the results obtained, the magnitude of the displacement of the operating point and the smoothing coefficient of the filter are determined, for which, for a given compaction in time, the energy loss relative to the ideal case will be minimal.
