摘要： The present invention provides a synchronization signal receiving method, including: receiving, by a receive end, a synchronization sequence sent by a transmit end, where the synchronization sequence includes a carrier frequency synchronization sequence, the carrier frequency synchronization sequence is zc(m)=e±jπm(m+1+2q)/L, m=0, 1, . . . , L−1, qεZ, L indicates a length of the carrier frequency synchronization sequence, q indicates a parameter of the carrier frequency synchronization sequence, Z indicates an integer set, e±jπm(m+1+2q)/L indicates the (±jπm(m+1+2q)/L)th power of e, and e is a natural constant; and performing, by the receive end, frequency offset estimation according to the received synchronization sequence, to obtain a frequency offset estimation value. With the technical solutions of embodiments of the present invention, accuracy of frequency offset estimation can be improved.
