Abstract:In this paper we compare different pulse shaping techniques for ICI (inter-carrier interference) reduction in dual-hop OFDM based Decode-and-Forward (DF) relay system. For that purpose, analytical derivation of closed-form bit error probability relations is presented. Scenarios corresponding to downlink communication in cellular systems are considered, assuming Ricean flat fading channel on the first hop, and time selective fading channel on the second hop. Two different fading statistics are analyzed for the … Show more
