It is proposed a receiver of SEFDM (Spectrally Efficient Frequency Division Multiplexing) in the case of frequency selective Rayleigh channel based on the representation of the SEFDM-signal as an equivalent OFDM-signal with reduced number of subcarriers. For demodulation of SEFDM-signal the BCJR algorithm is used. A study of SEFDM-signals behavior in Rayleigh multipath channel is done.
