Abstract
A process for determining a time lapse between a trigger signal and a start of a cyclic sequence of a pilot signal of a CDMA high frequency signal includes: simultaneously scanning and storing the trigger signal and the pilot signal; comparing the trigger signal with a trigger threshold to capture a time (t) to reach the trigger threshold; comparing the trigger signal with a trigger threshold to capture a time (t) to reach the trigger threshold; generating a CDMA baseband signal by transforming the CDMA high frequency signal into a complex baseband; correlating the CDMA baseband signal with a cyclic reference sequence to capture the time (t) up to the start of the cyclic sequence of the pilot signal; and subtracting tfrom tto determine the lapse in time.
