October 1979 | NTIA Technical Report TR-79-27
John R. Juroshek
Abstract: This report investigates the performance of an FM, landmobile, receiver in FM interference. Measurements are described showing the effects of multiple interfering FM signals as a function of modulation index, signal-to-interference ratio, signal-to-noise ratio, and frequency offset between the victim and interferer. The performance of the receiver is measured with various combinations of one to three interfering FM signals. The report also describes the spectra of the audio output during various interference conditions.
Keywords: land-mobile radio; interference; communications; frequency modulation; spectrum
