Title:
SIGNAL TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/051278
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and apparatus. The method comprises: obtaining 2N first signals and 2N-1 second signals, wherein both each first signal and each second signal comprise M signal points, signal values of the signal points at even positions of the first signal are zero, signal values of the signal points at odd or even positions of the second signal are zero, N is a positive integer, and M is a positive even number; performing inverse fast Fourier transform (IFFT) or inverse Fourier transform (IFT) or fast Fourier transform (FFT) or Fourier transform (FT) on the 2N first signals and the 2N-1 second signals to determine 2N third signals and 2N-1 fourth signals, wherein each third signal comprises M signal points, and each fourth signal comprises M signal points; determining a fifth signal according to the 2N third signals and the 2N-1 fourth signals, wherein the fifth signal comprises M*2N signal points; and sending the fifth signal. According to the method provided in the present application, spectral efficiency can be improved without increasing power consumption.
