Abstract

The problem of acquiring harmonized digital dividend in the upper part of the UHF band is considered through modifying the existing DVB-T frequency plans, as derived from the Geneva Agreement in 2006 (GE06). A novel scheme is proposed to modify GE06 plans by providing the requirements in frequency channels and taking into account intra- and inter-country electromagnetic compatibility constraints, provisioning for harmonized spectrum for the digital dividend in a coordinated way. The proposed scheme provides near- optimal frequency plans through metaheuristic methods, namely genetic algorithms, simulated annealing and particle swarm optimization.
