摘要：

A novel stalk sequence assisted discrete Fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) waveform is proposed to suppress out-of band (OoB) emission. In the proposed scheme, a deterministic sequence, which functions as cyclic prefix (CP), is used to suppress OoB emission. A measure of continuity is proposed to determine the location of the static sequence to maximize the amount of OoB suppression. Perturbation is added to the static sequence to further improve phase continuity at block transitions. It is shown that the spectra of the proposed static sequence assisted waveforms are more compact that those of the conventional waveforms. A frequency offset estimation method using the static sequence is described and its performance is evaluated by simulations.
