| 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 ± jÀm ( m +1+2 q )/ L , m = 0,1,..., L - 1, q ˆˆ Z , 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 ± jÀm ( m +1+2 q )/ L indicates the (± jÀm ( m +1+2 q )/ 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. |
