Method, apparatus, and system for time synchronization

摘要

A method, apparatus, and system for time synchronization in an OFDM are disclosed. The method comprising: obtaining a master sending time stamp, a slave receiving time stamp, a slave sending time stamp, and a master receiving time stamp; and adjusting the time of a slave clock according to the offset calculated from the time stamps to synchronize with a clock time of the master clock. With the present invention, in passband transmission systems that transmit signals continuously in units of symbols, the time synchronization is implemented between the master clock and the slave clock.
