Abstract: Data modulation for use in a multi-carrier system, a demodulation method, a frame generation method, and a node. 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.

Abstract: Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence. The output sequence corresponds to an output of a convolutional modulation between a set of coefficients and an intermediate sequence. The intermediate sequence is generated by inserting N zero coefficients between coefficients of the input sequence. The number of non-zero coefficients in the set of coefficients is based on N, N being a positive integer. Values of the non-zero coefficients correspond to values between 0 to π/2 to reduce a peak to average power ratio of the output sequence. The method also includes generating a waveform using the output sequence.
