Abstract
Embodiments of the present invention relate to the field of communications technologies, and disclose methods for generating and processing a frequency division multi-waveform signal, and apparatuses, which enable one system to support multiple multicarrier technologies at the same time. The method for generating a frequency division multi-waveform signal provided in the embodiments of the present invention includes: mapping first-type to-be-sent data streams to subcarriers corresponding to a first waveform component to generate M frequency domain symbols, and mapping second-type to-be-sent data streams to subcarriers corresponding to a second waveform component to generate N frequency domain symbols, where M and N are both positive integers; performing frequency domain filtering on the M frequency domain symbols and the N frequency domain symbols; and generating a time domain signal from the M frequency-domain-filtered frequency domain symbols and the N frequency-domain-filtered frequency domain symbols.
