Abstract:

SEFDM-signals (Spectrally Efficient Frequency Division Multiplexing) are considered as the main alternative to OFDM-signals in 5G networks. To our knowledge, at the present time there are no papers in which the analysis of BER performance of SEFDM-signals in AWGN channel is performed for optimal reception schemes. Such analysis is needed to carefully evaluate the suboptimal reception algorithms. In this paper the optimal reception schemes for SEFDM-signals are proposed. They are implemented in simulation model in Matlab. BER performance of SEFDM in AWGN channel for BPSK, QPSK and QAM-16 for various frequency spacing is simulated, the main factors affecting it are analyzed.
