| Abstract: | In this paper, we proposed an optimization method for the single frequency network in digital terrestrial television broadcasting system based on genetic algorithm, and analyzed the complexity of this method. We investigated the parameters of the proposed method on their respective impact of the algorithm complexity, thus ensure to achieve the best optimization results while still requiring the low cost. |
