Abstract
A wireless communication system having a time synchronization mechanism is provided. The wireless communication system comprises a first receiver and a second receiver. The first receiver tracks a code phase data of a satellite to generate a synchronization data related to a sync phase position and a first receiver phase position corresponding to one of first receiver time pulses. The second receiver comprises a receiving unit, a tracking unit and a computing unit. The receiving unit receives the synchronization data from the first receiver through a network. The tracking unit tracks the code phase data of the satellite to obtain a second receiver phase position corresponding to one of second receiver time pulses. The computing unit performs a time synchronization process with the first receiver and the satellite according to the code phase data, the synchronization data and the second receiver phase position.
