In single-frequency network (SFN) broadcasting systems, the presence of several transmitters translates into an equivalent channel with relevant sparsity in the delay domain, which may significantly impair the error performance. In DVB-H systems this channel sparsity, coupled with the time variation due to mobile users, renders the channel estimation task very challenging, especially when only a moderate complexity is tolerated at the receiver side. To solve this problem, this work proposes adoi:10.1109/spawc.2009.5161771 fatcat:xwj3vnehszh5ldzjhnlyqmhxcm
