    摘要： The method for tracking a mobile communication signal, which operates in a code division multiple access wireless communication system including an antenna (401), and a base site receiver (400) having at least two receiver tracking fingers (F1, F2), includes receiving at the antenna (401) a first multipath signal (119) arriving at an on-time pn-offset (706) with an associated advanced pn-offset value (704) and retard pn-offset value (702) and receiving at the antenna (401) a second multipath signal (107) arriving at an on-time pn-offset (712) with an associated advanced pn-offset value (710) and retard pn-offset value (708). The method further includes determining a spacing between the first multipath signal and the second multipath signal, and adjusting the at least two receiver tracking fingers based on the advanced pn-offset value of one of the multipath signals and the retard pn-offset value of the other multipath signal.
