Abstract: Methods, apparatus, and systems for efficiently utilizing scattered narrow spectra without introducing interreference among adjacent frequency bands are described. In one example aspect, a wireless communication method includes determining a set of time-domain symbols by applying an inverse Fourier transform to data modulated on multiple subcarrier groups. Each subcarrier group comprises one or more subcarriers and adjacent subcarrier groups are separated by one or more unused subcarriers, and each symbol has a symbol length of T0. The method includes determining a set of modulated time-domain symbols each having a length of N×T1 by modulating the set of time-domain symbols using a waveform function, where N is a real number greater than 1. The method includes transmitting the set of modulated time-domain symbols.

Abstract: A multicarrier system and data modulation and demodulation methods and devices for the multicarrier system are provided. The data modulation method includes: performing cyclic shifting on data sequences of L continuous symbols respectively, L≥2; and modulating the cyclically shifted data sequences by use of a waveform function, an independent variable range of the waveform function being greater than or equal to a symbol interval of the L modulated symbols. The technical solution solves the technical problems in which the related art is not compatible with a LTE system or effectively suppressing out-of-band leakage or flexibly adjusting a symbol interval to adapt to different channel environments and exhibits poor demodulation performance, thus achieving effective suppression of the out-of-band leakage, having higher compatibility with the LTE system and improving demodulation performance and flexibility of adjusting a symbol interval by simple cyclic shifting.
