First Claim
Patent Images
1. A method of monitoring stability of an on-frequency repeater, the method comprising steps of:
- generating a wide-band signature (WBS) signal associated with the repeater;
inserting the WBS signal into an output RF signal transmitted by the repeater;
extracting signal components corresponding to the WBS signal in an input RF signal received by the repeater; and
estimating a feedback path loss L using the isolated signal components.

Abstract
In a system for monitoring stability of an on-frequency repeater, a wide-band signature (WBS) signal associated with the repeater is generated, and inserted into an output RF signal transmitted by the repeater. Signal components corresponding to the WBS signal in an input RF signal received by the repeater are detected and analyzed to estimate a feedback path loss L.
