E. N. Smirnova scite author profile

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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
