ABSTRACT:
A method is provided for fast acquisition in a wireless network. This method involves receiving a first wireless signal at a receiving device, sent from a transmitting device; determining a first transmitting clock phase of the transmitting device by performing first acquisition and tracking processes on the first wireless signal; storing the first transmitting clock phase in the receiving device; receiving a second wireless signal at a receiving device, sent from the transmitting device after the first wireless signal; and determining a second transmitting clock phase of the transmitting device by performing a second acquisition process on the second wireless signal using the first transmitting clock phase as starting phase data. By using the stored first transmitting clock phase information as a starting point for acquisition, the receiving device can perform a second acquisition process that is much faster than a blind acquisition.
