Title: Signal quality measurement using full-complex FM detector

Abstract: A signal quality indicator for frequency modulated or phase modulated communication signals is obtained using a full-complex detector. The noise detector looks at the actual signal of interest and not other outside indicators such as high frequency content. Signal quality is measured accurately and efficiently. The resulting measure is used to control subsequent processing such as stereo blend, noise blanking, diversity antenna switching, and others in an FM radio receiver.
