METHOD AND SYSTEM FOR ESTIMATING TIME OF ARRIVAL OF SIGNALS USING MULTIPLE DIFFERENT TIME SCALES

摘要

A method and system (500) estimates a time of arrival of a signal received via a wireless communications channel. The energy in the received signal is conditioned at multiple different time scales to produce a conditioned signal (700). Then, a leading edge is detected in the conditioned signal (550). The leading edge corresponds to the time of arrival of the received signal (551).
