Design of DAB/DVB Based Multimedia Radio Networks for Mixed Broadcasting and Personal Services

Abstract [en]

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 broad­  casting 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  distribution of electronic multimedia newspapers to its sub­  scribers or the premium quality mobile Internet access,  where DAB/DVB network is used as a shared broadband  downlink channel. The total capacity demand of the user  population and its spatial distribution have to be taken into  account when planning the radio coverage for DAB/DVB  networks. In this paper we formulate the network planning  problem with this additional requirement as an optimization  problem, where the objective is to minimize the network  cost while satisfying both the capacity and the signal quality  constraints. 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.
