However, it is also one of the critical user cases, since, besides the vehicle penetration loss, the received signal quality is strongly affected by the high mobility of the users, which is accompanied by temporary shadowing and fast fading. On the other hand, mobility can be also beneficial thanks to the bursty character of DVB-H transmissions, as additional repair data can be sent in the time intervals between original service bursts in order to hide the coverage discontinuities from the users' perception. In this way, users which miss the original transmission have more chances to receive the information correctly. By managing the amount of repair data the network operator can trade system capacity and network latency for improved vehicular user satisfaction in a DVB-H network with imperfect coverage of the service area (as perceived by the vehicular users). To illustrate the potential of this approach, we evaluate the mentioned trade-off in a DVB-H system dimensioned for pedestrian outdoor users, for both streaming and f

In particular, we investigate the delivery cost savings that can be achieved using HSDPA and MBMS to repair https://www.researchgate.net/publication/220971456_RRM_for_Filecasting_Services_in_Hybrid_DVB-H3G_Systems errors of the initial DVB-H broadcast transmission. In a realistic scenario, there may be users that experience significantly worse DVB-H reception conditions than the majority, such that it may be more efficient to serve them through the cellular network. To enable an easy and efficient implementation of the repair mechanisms in the hybrid DVB-H/3G+ system, we adopt application layer forward error correction (AL-FEC) with Raptor coding. With AL-FEC specific packets are not required to be retransmitted, and repair transmissions consist of additional repair packets that can be used for all users. Hence, repair data can be seamlessly delivered with unicast HSDPA, multicast MBMS, and broadcast DVB-H transmissions. Furthermore, AL-FEC provides a multiburst protection of the DVB-H transmission to exploit the time diversity of the mobile broadcast channel.Discover the world's research10+ million members100+ million publications100k+ research projectsJoin for free FiguresEnlargeEnlargeEnlargeEnlarge+ 2
