ABSTRACT:
A diversity reception system for use in narrow-band radio frequency communication systems includes a plurality of receivers that each generate a detected signal from a received radio frequency signal. The diversity reception system switches between receivers to output a high quality audio signal. The system selects a receiver having the highest quality reception at any given time by using a detected signal having the highest relative signal-to-noise ratio when the detected signals have less than a preselected threshold signal-to-noise ratio and a detected signal having the highest relative signal strength when one or more of the receivers is generating a detected signal having a signal-to-noise ratio at or above the preselected threshold signal-to-noise ratio.
