tailieunhanh - Planning large single frequency networks for DVB-T2

The final coverage and associated performance of an SFN is a joint result of the properties of all transmitters in the SFN. Due to the large number of parameters involved in the process, finding the right configuration is quite complex. The purpose of the paper is to find optimal SFN network configurations for DVB-T2. Offering more options of system parameters than its predecessor DVB-T, DVB-T2 allows large SFN networks. However, self-interference in SFNs gives rise to restrictions on the maximum inter-transmitter distance and the network size. In order to make optimum use of the spectrum, the same frequency can be reused over different geographical areas - beyond the reuse distance to avoid co-channel interference. In this paper, a methodology based on theoretical network models is proposed. | ResearchGate See discussions stats and author profiles for this publication at https publication 275889930 Planning Large Single Frequency Networks for DVB-T2 Article in IEEE Transactions on Broadcasting September 2015 DOI CITATIONS 0 6 authors including Caiwei Li Beihang University BUAA 8 PUBLICATIONS 13 CITATIONS SEE PROFILE READS 387 Sato Telemi Institut fur Rundfunktechnik 3 PUBLICATIONS 0 CITATIONS SEE PROFILE Itziar Angulo Universidad del Pais Vasco Euskal Herriko Uni. 39 PUBLICATIONS 80 CITATIONS SEE PROFILE Pablo Angueira Universidad del Pais Vasco Euskal Herriko Uni. 147 PUBLICATIONS 566 CITATIONS SEE PROFILE All content following this page was uploaded by Pablo Angueira on 12 May 2015.
