Abstract
A diversity repeater that incorporates diversity diagnostic circuitry. The diversity diagnostic circuitry monitors the outputs of at least two receivers and determines the signal strength of the transmissions received by each receiver. If the signal strength for a particular receiver is below a predetermined threshold, the diversity diagnostic circuitry determines whether that receiver is receiving a rayleigh faded transmission or is an inoperative mode.
