On features of implementation of SEFDM-transmitter with optimal shape of envelope

This article describes joint use of two improving spectral efficiency algorithms for multi-frequency signals: SEFDM (Spectrally Efficient Frequency Division Multiplexing) technology and smoothed envelopes. SEFDM-signals are generated with IFFT algorithm. Transmitter with different envelope shapes is realized on SDR-platform HackRF One. Waveforms, spectra and PAPR (peak-to-average power ratio) of SEFDM-signals were obtained from simulation, vector signal generator and SDR-platform.
