Abstract

This study considers the transmission of digital signals in-band on-channel for application in Digital Audio Broadcasting (DAB). In the FM-channel used for analog transmission, two different DAB scenarios are simulated. In the first approach, the digital data is spread in form of a weak direct sequence spread spectrum (DSSS) signal underneath the FM. Since the FM signal is a multitone interference to the DSSS signal, it is to be excised. In this paper, a new adaptive frequency domain technique is proposed for excising multitone interference in DAB. The second scenario performs an amplitude modulation on the FM signal. This technique assures no interference inbetween the new, digital, and the already existing analog service.
