| Abstract: | In this paper, we proposed an optimization method for the single frequency network in digital terrestrial television broadcasting system using subchannels of physical layer to provide several services based on superposition coding. The proposed method improves the reception results of local services while still ensuring the requirements of global service, being of great importance in the full use of channel resource and reducing the computation complexity. |

| Keywords: | single frequency network (SFN) subchannel superposition coding genetic algorithm |
