Contribution to the study of single frequency network (SFN) coverage of digital terrestrial television DVB-T2 incorporating Mimo technology

The second-generation digital terrestrial television (DVB-T2) represents a key technology for large-scale audiovisual broadcasting, particularly in environments characterized by high population density and complex topography. One of the major challenges of this standard is the optimization of radio coverage while ensuring high spectral efficiency. Single Frequency Networks (SFNs) address these requirements by allowing multiple transmitters to simultaneously broadcast the same signal on the same frequency. However, SFN operation introduces constraints related to inter-symbol interference and multipath effects, especially in overlapping areas. The integration of MIMO (Multiple Input Multiple Output) technology into the DVB-T2 standard opens new perspectives for improving the robustness, capacity, and coverage of SFN networks. This article provides a contribution to the analytical and functional study of SFN coverage in DVB-T2 incorporating MIMO, relying on fundamental principles, channel modeling, spatial diversity mechanisms, and performance evaluation.
