摘　　要：首先介绍了单频网覆盖的判定准则,其次针对地面数字电视广播单频网的组网优化问题,提出了一种基于遗传算法的优化方法,并分析了算法的复杂度,着重探究算法参数对算法性能的影响,从而确保在得到最佳优化结果的同时付出最小的代价。The coverage criterion of single frequenay network is introduced in this paper. An optimization method for the single frequency network in digital terrestrial television broadcasting system based on genetic algorithm is proposed, and the complexity of this method is analyzed. The parameters of the proposed method on their respective impact of the algorithm complexity are investigated in order to achieve the best optimization results while still requiring the low cost.
