SYSTEM AND METHOD FOR DETECTING MULTIPATH EFFECTS IN A GPS RECEIVER

摘要

A multipath component in a GPS signal received is detected when an asymmetry exists in the correlation function of the received signal and the expected GPS signal. The multipath component is also detected, even without a line-of-sight component in the received GPS signal, when a peak of the correlation function jumps a significant distance (i.e., a sudden, significant change in a detected code phase).
