Single Frequency Network Planning for Dab/dvb with Individual Data Services
نویسنده
چکیده
Introduction of services for individual users in DAB/DVB networks imposes new demands on the network architecture. The total capacity demand of the user population and its spatial distribution have to be taken into account when planning the DAB/DVB network. In this paper we formulate this new planning problem as an optimization problem, where the objective is to minimize the network cost while satisfying both capacity and signal quality requirements of the users. We also propose an efficient heuristic algorithm that uses linear programming steps to iteratively build the network. We demonstrate that such a simple algorithm can provide solutions in affordable time for DAB/DVB planning problems of practically interesting complexity.

Design of DAB/DVB Based Multimedia Radio Networks for Mixed Broadcasting and Personal Services
| The introduction of personal services besides conventional broadcasting in DAB/DVB networks imposes new demands on the network architecture. The term \per-sonal service" means that some portion of the digital broadcasting bandwidth is reserved for transmitting information that is intended to only a limited number of users, or to only a single receiver. Examples for such services are the distr...
متن کاملSingle Frequency Network Planning
Both Digital Audio Broadcasting (DAB) and Digital Video Broadcasting (DVB) systems use orthogonal frequency division multiplexing (OFDM) to facilitate single frequency networks (SFNs). In an SFN all transmitters transmit the same information in the same frequency block simultaneously. This transmitter diversity structure makes SFNs very efficient in fading channels with an excellent spectrum sa...
متن کاملDRM - the BBC World Service distribution chain
At the basic RF-channel level, DRM shares many characteristics with other modern systems such as DVB-T and DAB. It utilises Coded Orthogonal Frequency Division Multiplexing (COFDM) [1][2] to combat noise, narrowband fading and multipath. Broadcasts can be synchronized to support Single-Frequency Networks (SFNs) and Multi-Frequency Networks (MFNs). One DRM service normally occupies one AM channe...
متن کاملOFDM receivers - impact on coverage of inter-symbol interference and FFT window positioning
The digital broadcasting systems DVB-T and T-DAB commonly exploit the single-frequency network (SFN) technique. In such networks, the treatment of inter-symbol interference and the synchronization strategy of the receivers is a crucial aspect in planning the networks and achieving the desired coverage. This is valid in two senses. ! Firstly, the performance of the receiver is strongly dependent...
متن کاملDigital Broadcasting in Slovenia - Implementation of spectrum planning policy on regional scale
In the following paper the perspectives of spatial development of digital broadcasting in Slovenia will be presented. Digital broadcasting will be considered in two main streams – digital audio broadcasting and digital video broadcasting, both in the terrestrial mode. In the field of digital radio, T-DAB frequency block allotments were already coordinated at the Wiesbaden planning conference in...
