Abstract :
Digital Radio Mondiale (DRM) is an OFDM-based digital radio broadcasting system for the frequency bands below 30MHz. ODFM systems are sensitive to synchronization errors, which cause inter-carrier interference (ICI). In this paper, a frame detection algorithm and FFT window point tracking method for low-power portable DRM´ receivers are presented.
