A transmitter node performs an inverse fast Fourier transform (IFFT) on successive L symbols of frequency domain data, wherein an inverse of an adjacent subcarrier interval of the frequency domain data is T0, and L≥2. The transmitter node modulates, using a designated wave function, the successive L symbols of time domain data generated after the IFFT process, wherein an adjacent symbol interval of the L symbols after the modulation is T1, and T1>T0. A variable interval length of the designated wave function is N×T1, where N is a real number exceeding or equal to 2 or 3. The application also provides the corresponding demodulation method, frame generation method, and node. The application can better inhibit out-of-band power leakage, and maintain compatibility to LTE. Furthermore, an increased demodulation performance is provided at a receiver end."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data modulation for use in multi-carrier system, demodulation method, frame generation method, and node","description":"Data modulation for use in a multi-carrier system, a demodulation method, a frame generation method, and a node.
