Abstract: The method includes: obtaining 2N first signals and 2N−1 second signals, where the first signal and the second signal each include M signal points, a signal value, at an even location, of the signal point of the first signal is 0, a signal value, at an odd location or an even location, of the signal point of the second signal is 0, N is a positive integer, and M is a positive even number; performing inverse fast Fourier transform IFFT, inverse Fourier transform IFT, 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.
