Abstract :
This paper deals with coexistence of DRM digital audio and FM analog audio broadcasting systems. Both types of interference are considered - signal of DRM digital system interfered by FM analog broadcasting system signal and analog FM signal interfered by digital DRM signal. Minimal useful signal to interference power ratio at the RF input is observed in case of useful DRM signal. Signal to noise power ratio at the LF output is measured in case of useful FM signal. Additionally sensitivity of receivers of both systems is measured.
