1. A base station, comprising:
a processor, configured to obtain a first set of discrete Fourier frequency coefficients Hu, and transform the first set of discrete Fourier frequency coefficients Hu into a time domain signal, wherein the first set of discrete Fourier frequency coefficients Hu is of m frequency shifts from a second set of discrete Fourier frequency coefficients {tilde over (H)}u, m is an integer except zero, the second set of discrete Fourier frequency coefficients {tilde over (H)}u corresponds to a number sequence du[n], n=0, 1, . . . , L−1, the length of the number sequence is L, the number sequence is centrally symmetric around an element n=(L−1)/2 of the number sequence, L is an odd positive integer and n denoting an element index of the number sequence; a transmitter, configured to transmit the time domain signal for facilitating synchronization in the wireless communication system. |
