Experimental research of receiver based on SEFDM-signals with optimal envelopes

Abstract This article describes a research of receiver which is part of SDR-modem based on SEFDM-signals (Spectrally Efficient Frequency Division Multiplexing) with optimal envelopes. Three envelope types and two values of frequency spacing between subcarriers in SEFDM-signals are implemented. Influence of combined use of methods of increasing spectral efficiency on BER performance is considered. Receive algorithm of SEFDM-signals is symbol-by-symbol coherent detection algorithm.
