Abstract
A signal synchronization method includes sending a narrowband signal, where a PPDU of the narrowband signal includes at least one pilot symbol, and the pilot symbol and the PPDU are used by a receiving device to obtain time-frequency synchronization information of an ultra-wideband signal, and sending the ultra-wideband signal. A carrier frequency offset is estimated based on these inserted pilot symbols and a preamble in the PPDU.
