In this paper, we present a coding strategy for wireless relay networks, where we assume no channel knowl-edge. More precisely, the relays operate without knowing the channel that affected their received signal, and the receiver decodes knowing none of the channel paths. The coding scheme is inspired by noncoherent differential space-time coding, and is shown to yield a diversity linear in the number of relays. It is furthermore available for any number of relay nodes.
