Abstract:
1. A method for synchronizing to one or more signals in a positioning system, the method comprising: determining if sufficient a priori information on time or position associated with the signals is known; setting a target probability of false alarm (Pfa) to a first value if the a priori information is determined to be not sufficient and setting the target Pfa to a second value that is less strict than the first value if the a priori information is determined to be sufficient; setting thresholds for determining if data bit synchronization has been achieved in accordance with the target Pfa that has been set based on the determination of the a priori information; and performing, by a positioning device having a receiver for receiving the signals, data bit synchronization using the signals and the thresholds that have been set in accordance with the target Pfa.
