Abstract

A study of Spectrally Efficient Frequency Division Multiplexing (SEFDM) signals generation is done. Three new algorithms for generation and reception of SEFDM-signals based on FFT/IFFT are proposed. Their complexity and conditions of applicability are analyzed. It is shown that the proposed schemes outperform the proposed earlier by 1,2-6 times. The BER performance of the developed methods for AWGN channel is analyzed, it is shown that the number of the guard subcarriers significantly affects the BER performance of SEFDM (up to 4 dB energy loss when doubling the guard part of the signal).
