Abstract :
A mathematical model is developed that can be used to analyze the effects of multipath on any modulation of an FM carrier. The predictions of this model are verified by simulation and by actual field testing. The model is used to analyze the existing FM stereo system and the proposed FMX system. The analysis, confirmed by field tests in over 15 000 locations, shows that FMX transmission significantly degrades reception on existing FM stereo receivers and that FMX receivers are inferior to FM stereo receivers for receiving FMX transmissions
