description: In this work, we propose utilization of RRC pulses and optimal pulses as shape of subcarrierâs spectrums for SEFDM signals. We suggested algorithms to generate and detect SEFDM signals in frequency domain. For this purpose, frequency-domain samples of signal are considered as time-domain samples. Optimal spectral pulses are obtained by the linear optimization. The criterion of optimization is maximizing the normalized squared Euclidean distance. Additional constraints are the amount of bandwidth comprising 99,9% of signal power and non-negativity of the energy spectrum. We used the Viterbi and M-BCJR algorithms for signal detection under assumption of additive white Gaussian noise channel. The simulation results have shown that signals with optimal spectral pulses provide significant gain in spectral efficiency comparing to OFDM and RRC-SEFDM. This gain is achieved under fixed computational complexity of the detection algorithm.
