In this paper some simple cooperative relaying strategies which rely on the exploitation of the Delay Diversity technique and the Maximal Ratio Combining (MRC) receive diversity algorithm are proposed for a DVB-SH compliant hybrid satellite/terrestrial network. These strategies are investigated in a public emergency scenario where the adoption of an integrated heterogeneous network combined with the cooperative diversity techniques guarantees the connection between the incident area and the external areas: particularly, the drawbacks of the Non-Line-Of-Sight (NLOS) propagation are mitigated. The NAV/COM capabilities of the cooperative DD algorithm in a DVB-SH Single Frequency Network (SFN) are discussed, highlighting the suitability of these schemes in emergency situation management. A comparison analysis of the proposed schemes is performed, describing the assumptions required and the simulation results with respect to the satellite-only and the terrestrial-only cases. © Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering 2010.
