ABSTRACT:
A multipath signal strength indicator is included in a communications receiver which is responsive to a communications channel subject to a multipath signal. The multipath signal strength indicator includes circuitry for estimating the characteristics of the communications channel and circuitry for storing nominal characteristics of a communications channel free of the multipath signal. Further circuitry calculates the difference between the nominal characteristic and the estimated channel characteristic as the multipath signal strength.
