REPEATER IDENTIFICATION IN POSITION DETERMINATION SYSTEM |
摘要 |
A method of identifying whether a first signal received at a subscriber station has been relayed by a repeater. The method involves measuring at the subscriber station a time difference of arrival between the first signal and a second signal. A hyperboloid or other potential solution surface is then formed from the measured time difference of arrival. A determination is then made whether or not the first signal was relayed by a repeater based on information derived from the potential solution surface. |
