Genetic Algorithm Based Optimization Method of Single Frequency Network Planning for DTMB

In this paper, an approach to optimization of the single frequency network (SFN) for Digital Television Terrestrial Multimedia Broadcasting (DTMB) is proposed, aiming to resolve the issue that the design and construction of SFN is complex and time-consuming. The approach can be used to balance the performance and cost of an overlay network, and adopt the genetic algorithm to jointly optimize the delays of all transmission stations within it, then eventually create multiple SFN solutions that are optional to address the requirements on specific covered area and population located in a given region, thus considerably improving the efficiencies of SFN design and construction. The results of our tests indicate that the outcomes of SFN coverage optimization were measurably improved with the genetic algorithm for delay optimization of the transmission stations.
